Three types of the mat-files were uploaded for each monkey.<br />
<br />
A '''"ECoG_chXXX.mat"''' contains ECoG signal recorded from the channel XXX (XXX =001-128). Loading each file, you'll obtain the matrix "data" that is the 2D matrix of trial*time. Each row is an ECoG signal for each trial starting from 1 sec before the onset of the fixation point (FP) onset. Thus for example, you can draw ERP assigned to the FP onset by plot(mean(data,1)).<br />
<br />
B '''"info.mat"''' contains "prms" (struct) and "eyeData" (cell). "prms" is the time-stamps of the events and the task parameters (see below ''i)'' for the details) for each trial. The time zero is the timing of the FP onset. For the trials in which the monkey was waiting for the FP onset around the center of the display before the FP turned on, prms.fixStart(n) became 1. "eyeData" contains the horizontal and vertical eye positions in each trial. Note that the sampling rate of the eye positions was 500 Hz that is different from that for ECoG signals (1 kHz).<br />
<br />

<br />
tgPolarAngle: the polar angle of the ST position<br />
<br />
tgEcc: the eccentricity of the ST position<br />
<br />
<br />
ii) Basically we adopted the block-design. Each block contained about a few hundred trials. Within a block, the position of the target was fixed in terms of the eccentricity, and the number of the possible positions was 4 for each block, which means, the polar angle of the target was 45, 135, 225, or 315 in some blocks, and 90, 180, 270 or 360 in the other blocks.<br />
<br />
<br />
C '''"elPosition_XX.mat"''' is the information about the location of the electrodes on the cortical surface (XX = Qu, Bt. or Cn). You can see the location of the electrodes with the code like this;<br />

Three types of the mat-files were uploaded for each monkey.<br />
<br />
A '''"ECoG_chXXX.mat"''' contains ECoG signal recorded from the channel XXX (XXX =001-128). Loading each file, you'll obtain the matrix "data" that is the 2D matrix of trial*time. Each row is an ECoG signal for each trial starting from 1 sec before the onset of the fixation point (FP) onset. Thus for example, you can draw ERP assigned to the FP onset by plot(mean(data,1)).<br />
<br />
B '''"info.mat"''' contains "prms" (struct) and "eyeData" (cell). "prms" is the time-stamps of the events - such as the timing of the fixation start, the reward delivery, the target onset, the start of the saccade (detected online) - and the information of the target - polar angle and eccentricity - for each trial. The time zero is the timing of the FP onset. For the trials in which the monkey was waiting for the FP onset around the center of the display before the FP turned on, prms.fixStart(n) became 1. "eyeData" contains the horizontal and vertical eye positions in each trial. Note that the sampling rate of the eye positions was 500 Hz that is different from that for ECoG signals (1 kHz).<br />
<br />
Basically we adopted the block-design. Each block contained about a few hundred trials. Within a block, the position of the target was fixed in terms of the eccentricity, and the number of the possible positions was 4 for each block, which means, the polar angle of the target was 45, 135, 225, or 315 in some blocks, and 90, 180, 270 or 360 in the other blocks.<br />
<br />
C '''"elPosition_XX.mat"''' is the information about the location of the electrodes on the cortical surface (XX = Qu, Bt. or Cn). You can see the location of the electrodes with the code like this;<br />

<br />
<br />
== Q) Do the values in 'Ain' mean anything besides event? (ex. 1652 and 1653 in Stimulus4 are same or different?) ==<br />
<br />
A) Because of noise, the amplitude of signal was fluctuated. <br />
<br />
1652 and 1653 in Stimulus4 were same (the all values in 1600-1700 belonged to<br />
Stimulus4).<br />
<br />
== Q) What was the size of the visual stimulus/display? (in terms of the horizontal and vertical angles, or the actual size - I will convert it to the visual angles, assuming that the distance between the monkey and screen was 490mm.) ==<br />
<br />
A) Display resolution: 1920×1200<br />
<br />
Display Size: 518.4×324.0mm<br />
<br />
Spatial frequency: 0.01cycle/pixel<br />
<br />
The interval of grating: 27mm<br />
<br />
Time frequency: 4Hz<br />
<br />
Moving velocity: 108 mm/sec<br />
<br />
== Q) Do the angles (0,0) correspond to the center of the visual stimulus? ==<br />
<br />
A) Yes. To be more precise, it corresponds to the center of the movie.<br />
In the experiment, I tried to match the center of the movie with the center of the stimuli.</div>WikiSysophttps://wiki.neurotycho.org/index.php?title=Fixation_Details&diff=86137Fixation Details2016-02-08T05:45:57Z<p>WikiSysop: </p>

<br />
Three types of the mat-files were uploaded for each monkey.<br />
<br />
A "ECoG_chXXX.mat" contains ECoG signal recorded from the channel XXX (XXX =001-128). Loading each file, you'll obtain the matrix "data" that is the 2D matrix of trial*time. Each row is an ECoG signal for each trial starting from 1 sec before the onset of the fixation point (FP) onset. Thus for example, you can draw ERP assigned to the FP onset by plot(mean(data,1)).<br />
<br />
B "info.mat" contains "prms" (struct) and "eyeData" (cell). "prms" is the time-stamps of the events, the fixation start and the reward delivery, for each trial. "eyeData" contains the horizontal and vertical eye positions in each trial. Note that the sampling rate of the eye positions was 500 Hz that is different from that for ECoG signals (1 kHz).<br />
<br />
C "elPosition_XX.mat" is the information about the location of the electrodes on the cortical surface (XX = Qu, Bt. or Cn). You can see the location of the electrodes with the code like this;<br />
<br />
load('elPosition_Qu.mat');<br />

- Data format<br />
We prepared 3 kinds of the mat-files for each monkey.<br />
<br />
A. "ECoG_chXXX.mat" contains ECoG signal recorded from the channel XXX (XXX = 001-128). Loading each mat file, you'll obtain a matrix "data" that is a 2D matrix of trial*time. Each row is a ECoG signal in one trial starting 1sec before the onset of fixation point (FP). Thus for example, you can draw ERP assigned to the FP onset by plot(mean(data,1)).<br />
<br />
B. "info.mat" contains 2 variables "prms" (struct) and "eyeData" (cell). "prms" contains the 2 types of the event stamps, the timing of the fixation start and the reward delivery in each trial. Note that the origin of the time is the FP onset. "eyeData" contains the horizontal and vertical eye positions in each trial. Note that the sampling rate for the eye-positions was 500 Hz, while the sampling rate for ECoG signals was 1 kHz.<br />
<br />
C. "elPosition_XX.mat" contains the information about the electrodes-location in monkey XX (XX =Qu, Bt, or Cn). You can see the electrode locations on the brain surface with the code like this;<br />
load("elInfo.mat");<br />

ECoG data was in ECoG-*.mat.<br />
ECoG signals are in 1st-128th rows and the event information is in 129th row.<br />
<br />
The brainmap of each monkey was in the folder "BrainMap".<br />
<br />
I also sent you a matlab script "ExtractEyeTrack4.m" which demonstrate how to use the eye-tracking data.<br />
Please edit a path of files and select a monkey and an ExpID in ExtractEyeTrack4.m.<br />
A movie file is available for only ExpID= '100723'.<br />
<br />
<br />
Eye-track data is in Take*.csv.<br />
<br />
The third column has a horizontal angle of eye-gaze and the forth column has a vertical angle of eye-gaze.<br />
In the script I transformed the angles to the position of movie (pixel).<br />
The nineth column has a flag to check whether monky's eye was open or close.<br />
When the value was zero, monkey's eye was open.<br />
The sampling rate of eye-tracking system (Vicon system) was 119.8809 Hz and the sampling rate of movie is 29.97 Hz.<br />
<br />
<br />
You can see a sample movie in K2-100723V.mov<br />
<br />
<br />
Note.1 In the sample movie "K2-100723V.mov", there is small spatial gap between the position of eye-gaze recorded in the movie and the position of eye-gaze which is constructed by eye-tracking data. If you need more accuray, you can reduce the gap by adding some offsets.<br />
<br />
Note.2 The rate of eye-opened period (in which the eye-tracking system could detect the eye-gaze) is about 0.5 through the experiments. In the experiment, eye-tracking system didn't tune in monkey's eye. So the frequency eye-track system could not detect the eye-gaze increased. Even though we failed to recored the eye-gaze in the experiment, we monitered whether monkey's eye was open or not during the experiment and awaken the monkey when monkey's eye was closed. The image of monkey's eye was recorded in the lower right position of the movie.<br />
<br />
Note.3 In most of time in the experiment, monkey saw the periphery of display. But the display covered the most part of monkey's view. So even though monkey saw the periphery, we can presume that the peripery of visual cortex received the visual graging stimili.</div>WikiSysophttps://wiki.neurotycho.org/index.php?title=Visual_Grating_Task_Details&diff=86126Visual Grating Task Details2016-02-08T02:41:08Z<p>WikiSysop: </p>

ECoG data was in ECoG-*.mat.<br />
ECoG signals are in 1st-128th rows and the event information is in 129th row.<br />
<br />
The brainmap of each monkey was in the folder "BrainMap".<br />
<br />
I also sent you a matlab script "ExtractEyeTrack4.m" which demonstrate how to use the eye-tracking data.<br />
Please edit a path of files and select a monkey and an ExpID in ExtractEyeTrack4.m.<br />
A movie file is available for only ExpID= '100723'.<br />
<br />
Eye-track data is in Take*.csv.<br />
The third column has a horizontal angle of eye-gaze and the forth column has a vertical angle of eye-gaze.<br />
In the script I transformed the angles to the position of movie (pixel).<br />
The nineth column has a flag to check whether monky's eye was open or close.<br />
When the value was zero, monkey's eye was open.<br />
The sampling rate of eye-tracking system (Vicon system) was 119.8809 Hz and the sampling rate of movie is 29.97 Hz.<br />
<br />
You can see a sample movie in K2-100723V.mov<br />
<br />
Note.1 In the sample movie "K2-100723V.mov", there is small spatial gap between the position of eye-gaze recorded in the movie and the position of eye-gaze which is constructed by eye-tracking data. If you need more accuray, you can reduce the gap by adding some offsets.<br />
<br />
Note.2 The rate of eye-opened period (in which the eye-tracking system could detect the eye-gaze) is about 0.5 through the experiments. In the experiment, eye-tracking system didn't tune in monkey's eye. So the frequency eye-track system could not detect the eye-gaze increased. Even though we failed to recored the eye-gaze in the experiment, we monitered whether monkey's eye was open or not during the experiment and awaken the monkey when monkey's eye was closed. The image of monkey's eye was recorded in the lower right position of the movie.<br />
<br />
Note.3 In most of time in the experiment, monkey saw the periphery of display. But the display covered the most part of monkey's view. So even though monkey saw the periphery, we can presume that the peripery of visual cortex received the visual graging stimili.</div>WikiSysophttps://wiki.neurotycho.org/index.php?title=Main_Page&diff=86123Main Page2016-02-08T02:28:51Z<p>WikiSysop: </p>

<div>== Purpose ==<br />
<br />
In Anesthesia and Sleep task, we recorded electrocoticographic (ECoG) signals from most of the lateral cortex in four macaques during awake (eyes-opened, eyes-closed), anesthetic and sleeping conditions. By comparing neural activity in conscious state with unconscious state, you can find consciousness-correlated neural activity. This dataset enables you to test your "theory of consciousness".<br />
<br />

<br />
<br />
== Detail Method == <br />
<br />
*;Anesthesia Experiments<br />
<br />
We did 4 experiments in which the monkey was under anesthesia. Two anesthetic agents, ketamine and medetomidine, were used in the first experiment. In other experiments, only propofol, ketamine or medetomidine were used respectively. <br />
<br />
During the experiments, a monkey was seated in a primate chair with both arms and head movement restricted. Neural data were acquired during the experiment. There were three conditions that were awake, anesthetized and recovery conditions. The awake condition had eyes-opened and eyes-closed conditions. At first the monkey’s eyes were opened and the monkey would sit calmly for up to 20 min (See Table). Next the monkey’s eyes were covered by an eye-mask to refrain from evoking visual response. During the eyes-closed condition, the monkey would sit calmly for up to 20 min at which time we would start to monitor heart rate (See Table). <br />
<br />
In experiments where the ketamine-medetomidine cocktail was used to induce anesthesia, the ketamine (～5.0 mg/kg for M1–M3, 8.8 mg/kg for M4) and medetomidine (～0.016 mg/kg for M1–M3, 0.053 mg/kg for M4) were injected intramuscularly (see Table). In contrast, propofol-induced anesthesia was achieved through intravenous propofol (5.2 mg/kg for M1 and M2) injection (see Table). In ketamine-induced anesthesia experiment, the ketamine (～5.1 mg/kg for M1 and M2) was injected intramuscularly (see Table). In medetomidine-induced anesthesia experiment, the medetomidine (～0.018 mg/kg for M1 and M2) was injected intramuscularly (see Table).<br />
Loss of consciousness (LOC) was defined as the point at which the monkey no longer responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab. As an additional confirmation that the monkey had achieved LOC, we could observe slow wave oscillations in the neural signal. After LOC was established, neural activity was recorded for up to 30 min for the ketamine-medetomidine-induced anesthesia experiment, and about 10 min for the propofol-, ketamine-, and medetomidine-induced anesthesia experiments respectively (Anesthetized condition). Heart rate and breathing were monitored carefully throughout the length of the experiment. <br />
<br />
After the anesthetized condition, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for recovery. In the recovery condition, there were eyes-closed and eyes-opened conditions. In ketamine-medetomidine-induced anesthesia experiment, the onset of recovery eyes-closed condition was defined as the point at which the slow wave oscillation in the neural signal disappeared. In propofol-, ketamine- and medetomidine-induced anesthesia experiments, the onset of recovery eyes-closed condition was defined as the point at which the monkey responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab as same sensitivity as the awake eye-closed condition.<br />
<br />
During the recovery eyes-closed condition, the monkey’s eyes were closed and the monkey would sit calmly for 10～30 min. Next the monkey’s eyes were opened by removing the eye-mask. During the recovery eyes-opened condition, the monkey would sit calmly for about 10 min. <br />
<br />
We performed two to three experiments for each monkey, all on separate days (See Table).<br />
<br />
<br />
*;Natural Sleep Experiment<br />
<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />
<br />
EOG and EMG were performed at a sampling rate of 1 kHz by a Cerebus data acquisition system (Blackrock Microsystems, Salt Lake City, UT, USA)). EOG signals were recorded from the muscles of the right eye by placing 2 electrodes (Nihon Kohden, Disposable electrode for ECG Monitoring M-150) on near the outer and inner canthi of the right eye. The difference in potential between the 2 electrodes was then used as the EOG signal. Two electrodes were put on the chin, and the difference in the potential between these electrodes was used as the EMG signal.<br />
<br />
In the sleeping condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleeping condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 experiments were performed on separate days, respectively (See Table). The sleeping state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa et al. 2013 for the detail method).<br />

During the recovery eyes-closed condition, the monkey’s eyes were closed and the monkey would sit calmly for 10～30 min. Next the monkey’s eyes were opened by removing the eye-mask. During the recovery eyes-opened condition, the monkey would sit calmly for about 10 min. <br />
<br />
We performed two to three experiments for each monkey, all on separate days (See Table).<br />

<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />

In the sleeping condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleeping condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 experiments were performed on separate days, respectively (See Table). The sleeping state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa et al. 2013 for the detail method).<br />

<br />
This dataset was designed to find consciousness-correlated neural activity and functional connectivity by comparing conscious state with unconscious state. We recorded electrocoticographic (ECoG) signals from most of the lateral cortex in four macaques during awake (eyes-opened, eyes-closed), anesthetic and sleeping conditions.

== Detail Method == <br />
<br />
*;Anesthesia Experiments<br />
<br />
We did 4 experiments in which the monkey was under anesthesia. Two anesthetic agents, ketamine and medetomidine, were used in the first experiment. In other experiments, only propofol, ketamine or medetomidine were used respectively. <br />
<br />
During the experiments, a monkey was seated in a primate chair with both arms and head movement restricted. Neural data were acquired during the experiment. There were three conditions that were awake, anesthetized and recovery conditions. The awake condition had eyes-opened and eyes-closed conditions. At first the monkey’s eyes were opened and the monkey would sit calmly for up to 20 min (See Table). Next the monkey’s eyes were covered by an eye-mask to refrain from evoking visual response. During the eyes-closed condition, the monkey would sit calmly for up to 20 min at which time we would start to monitor heart rate (See Table). <br />
<br />
In experiments where the ketamine-medetomidine cocktail was used to induce anesthesia, the ketamine (～5.0 mg/kg for M1–M3, 8.8 mg/kg for M4) and medetomidine (～0.016 mg/kg for M1–M3, 0.053 mg/kg for M4) were injected intramuscularly (see Table). In contrast, propofol-induced anesthesia was achieved through intravenous propofol (5.2 mg/kg for M1 and M2) injection (see Table). In ketamine-induced anesthesia experiment, the ketamine (～5.1 mg/kg for M1 and M2) was injected intramuscularly (see Table). In medetomidine-induced anesthesia experiment, the medetomidine (～0.018 mg/kg for M1 and M2) was injected intramuscularly (see Table).<br />
Loss of consciousness (LOC) was defined as the point at which the monkey no longer responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab. As an additional confirmation that the monkey had achieved LOC, we could observe slow wave oscillations in the neural signal. After LOC was established, neural activity was recorded for up to 30 min for the ketamine-medetomidine-induced anesthesia experiment, and about 10 min for the propofol-, ketamine-, and medetomidine-induced anesthesia experiments respectively (Anesthetized condition). Heart rate and breathing were monitored carefully throughout the length of the experiment. <br />
<br />
After the anesthetized condition, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for recovery. In the recovery condition, there were eyes-closed and eyes-opened conditions. In ketamine-medetomidine-induced anesthesia experiment, the onset of recovery eyes-closed condition was defined as the point at which the slow wave oscillation in the neural signal disappeared. In propofol-, ketamine- and medetomidine-induced anesthesia experiments, the onset of recovery eyes-closed condition was defined as the point at which the monkey responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab as same sensitivity as the awake eye-closed condition.<br />
<br />
During the recovery eyes-closed condition, the monkey’s eyes were closed and the monkey would sit calmly for 10～30 min. Next the monkey’s eyes were opened by removing the eye-mask. During the recovery eyes-opened condition, the monkey would sit calmly for about 10 min. <br />
<br />
We performed two to three experiments for each monkey, all on separate days (See Table).<br />
<br />
<br />
*;Natural Sleep Experiment<br />
<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />
<br />
EOG and EMG were performed at a sampling rate of 1 kHz by a Cerebus data acquisition system (Blackrock Microsystems, Salt Lake City, UT, USA)). EOG signals were recorded from the muscles of the right eye by placing 2 electrodes (Nihon Kohden, Disposable electrode for ECG Monitoring M-150) on near the outer and inner canthi of the right eye. The difference in potential between the 2 electrodes was then used as the EOG signal. Two electrodes were put on the chin, and the difference in the potential between these electrodes was used as the EMG signal.<br />
<br />
In the sleeping condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleeping condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 experiments were performed on separate days, respectively (See Table). The sleeping state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa et al. 2013 for the detail method).<br />

After the anesthetized condition, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for recovery. In the recovery condition, there were eyes-closed and eyes-opened conditions. In ketamine-medetomidine-induced anesthesia experiment, the onset of recovery eyes-closed condition was defined as the point at which the slow wave oscillation in the neural signal disappeared. In propofol-, ketamine- and medetomidine-induced anesthesia experiments, the onset of recovery eyes-closed condition was defined as the point at which the monkey responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab as same sensitivity as the awake eye-closed condition.<br />
<br />
During the recovery eyes-closed condition, the monkey’s eyes were closed and the monkey would sit calmly for 10～30 min. Next the monkey’s eyes were opened by removing the eye-mask. During the recovery eyes-opened condition, the monkey would sit calmly for about 10 min. <br />
<br />
We performed two to three experiments for each monkey, all on separate days (See Table).<br />
<br />
<br />
*;Natural Sleep Experiment<br />
<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />
<br />
EOG and EMG were performed at a sampling rate of 1 kHz by a Cerebus data acquisition system (Blackrock Microsystems, Salt Lake City, UT, USA)). EOG signals were recorded from the muscles of the right eye by placing 2 electrodes (Nihon Kohden, Disposable electrode for ECG Monitoring M-150) on near the outer and inner canthi of the right eye. The difference in potential between the 2 electrodes was then used as the EOG signal. Two electrodes were put on the chin, and the difference in the potential between these electrodes was used as the EMG signal.<br />
<br />
In the sleep condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleep condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 experiments were performed on separate days, respectively (See Table). The sleep state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa et al. 2013 for the detail method).<br />

<br />
*;Anesthesia Experiments<br />
<br />
We did 4 experiments in which the monkey was under anesthesia. Two anesthetic agents, ketamine and medetomidine, were used in the first experiment. In other experiments, only propofol, ketamine or medetomidine were used respectively. <br />
<br />
During the experiments, a monkey was seated in a primate chair with both arms and head movement restricted. Neural data were acquired during the experiment. There were three conditions that were awake, anesthetized and recovery conditions. The awake condition had eyes-opened and eyes-closed conditions. At first the monkey’s eyes were opened and the monkey would sit calmly for up to 20 min (See Table). Next the monkey’s eyes were covered by an eye-mask to refrain from evoking visual response. During the eyes-closed condition, the monkey would sit calmly for up to 20 min at which time we would start to monitor heart rate (See Table). <br />
<br />
In experiments where the ketamine-medetomidine cocktail was used to induce anesthesia, the ketamine (～5.0 mg/kg for M1–M3, 8.8 mg/kg for M4) and medetomidine (～0.016 mg/kg for M1–M3, 0.053 mg/kg for M4) were injected intramuscularly (see Table). In contrast, propofol-induced anesthesia was achieved through intravenous propofol (5.2 mg/kg for M1 and M2) injection (see Table). In ketamine-induced anesthesia experiment, the ketamine (～5.1 mg/kg for M1 and M2) was injected intramuscularly (see Table). In medetomidine-induced anesthesia experiment, the medetomidine (～0.018 mg/kg for M1 and M2) was injected intramuscularly (see Table).<br />
Loss of consciousness (LOC) was defined as the point at which the monkey no longer responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab. As an additional confirmation that the monkey had achieved LOC, we could observe slow wave oscillations in the neural signal. After LOC was established, neural activity was recorded for up to 30 min for the ketamine-medetomidine-induced anesthesia experiment, and about 10 min for the propofol-, ketamine-, and medetomidine-induced anesthesia experiments respectively (Anesthetized condition). Heart rate and breathing were monitored carefully throughout the length of the experiment. <br />
<br />
After the anesthetized condition, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for recovery. In the recovery condition, there were eyes-closed and eyes-opened conditions. In ketamine-medetomidine-induced anesthesia experiment, the onset of recovery eyes-closed condition was defined as the point at which the slow wave oscillation in the neural signal disappeared. In propofol-, ketamine- and medetomidine-induced anesthesia experiments, the onset of recovery eyes-closed condition was defined as the point at which the monkey responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab as same sensitivity as the awake eye-closed condition.<br />
<br />

<br />

In propofol-, ketamine- and medetomidine-induced anesthesia experiments, the onset of recovery eyes-closed condition was defined as the point at which the monkey responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab as same sensitivity as the awake eye-closed condition.<br />
<br />
During the recovery eyes-closed condition, the monkey’s eyes were closed and the monkey would sit calmly for 10～30 min. Next the monkey’s eyes were opened by removing the eye-mask. During the recovery eyes-opened condition, the monkey would sit calmly for about 10 min. <br />
<br />
We performed two to three experiments for each monkey, all on separate days (See Table).<br />
<br />
<br />
*;Natural Sleep Experiment<br />
<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />
<br />
EOG and EMG were performed at a sampling rate of 1 kHz by a Cerebus data acquisition system (Blackrock Microsystems, Salt Lake City, UT, USA)). EOG signals were recorded from the muscles of the right eye by placing 2 electrodes (Nihon Kohden, Disposable electrode for ECG Monitoring M-150) on near the outer and inner canthi of the right eye. The difference in potential between the 2 electrodes was then used as the EOG signal. Two electrodes were put on the chin, and the difference in the potential between these electrodes was used as the EMG signal.<br />
<br />
In the sleep condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleep condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 experiments were performed on separate days, respectively (See Table). The sleep state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa et al. 2013 for the detail method).<br />

<br />
*;Anesthesia Experiments<br />
<br />
We did 4 experiments in which the monkey was under anesthesia. Two anesthetic agents, ketamine and medetomidine, were used in the first experiment. In other experiments, only propofol, ketamine or medetomidine were used respectively. <br />
<br />
During the experiments, a monkey was seated in a primate chair with both arms and head movement restricted. Neural data were acquired during the experiment. There were three conditions that were awake, anesthetized and recovery conditions. The awake condition had eyes-opened and eyes-closed conditions. At first the monkey’s eyes were opened and the monkey would sit calmly for up to 20 min (See Table). Next the monkey’s eyes were covered by an eye-mask to refrain from evoking visual response. During the eyes-closed condition, the monkey would sit calmly for up to 20 min at which time we would start to monitor heart rate (See Table). <br />
<br />
In experiments where the ketamine-medetomidine cocktail was used to induce anesthesia, the ketamine (～5.0 mg/kg for M1–M3, 8.8 mg/kg for M4) and medetomidine (～0.016 mg/kg for M1–M3, 0.053 mg/kg for M4) were injected intramuscularly (see Table). In contrast, propofol-induced anesthesia was achieved through intravenous propofol (5.2 mg/kg for M1 and M2) injection (see Table). In ketamine-induced anesthesia experiment, the ketamine (～5.1 mg/kg for M1 and M2) was injected intramuscularly (see Table). In medetomidine-induced anesthesia experiment, the medetomidine (～0.018 mg/kg for M1 and M2) was injected intramuscularly (see Table).<br />
Loss of consciousness (LOC) was defined as the point at which the monkey no longer responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab. As an additional confirmation that the monkey had achieved LOC, we could observe slow wave oscillations in the neural signal. After LOC was established, neural activity was recorded for up to 30 min for the ketamine-medetomidine-induced anesthesia experiment, and about 10 min for the propofol-, ketamine-, and medetomidine-induced anesthesia experiments respectively (Anesthetized condition). Heart rate and breathing were monitored carefully throughout the length of the experiment. <br />
<br />
After the anesthetized condition, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for recovery. In the recovery condition, there were eyes-closed and eyes-opened conditions. In ketamine-medetomidine-induced anesthesia experiment, the onset of recovery eyes-closed condition was defined as the point at which the slow wave oscillation in the neural signal disappeared. In propofol-, ketamine- and medetomidine-induced anesthesia experiments, the onset of recovery eyes-closed condition was defined as the point at which the monkey responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab as same sensitivity as the awake eye-closed condition.<br />
<br />
During the recovery eyes-closed condition, the monkey’s eyes were closed and the monkey would sit calmly for 10～30 min. Next the monkey’s eyes were opened by removing the eye-mask. During the recovery eyes-opened condition, the monkey would sit calmly for about 10 min. <br />
<br />
We performed two to three experiments for each monkey, all on separate days (See Table).<br />

<br />
We did 4 experiments in which the monkey was under anesthesia. Two anesthetic agents, ketamine and medetomidine, were used in the first experiment. In other experiments, only propofol, ketamine or medetomidine were used respectively. <br />
<br />
During the experiments, the monkey was seated in a primate chair with both arms and head movement restricted. Neural data were acquired during the experiment. There were three conditions that were awake, anesthetized and recovery conditions. The awake condition had eyes-opened and eyes-closed conditions. At first monkey’s eyes were opened and the monkey sat calmly for up to 20 min. Next the monkey’s eyes were covered by an eye-mask to refrain from evoking visual response. During the eyes-closed condition, the monkey would sat calmly for up to 20 min at which time we would start to monitor heart rate. <br />
<br />
In experiments where the ketamine-medetomidine cocktail was used to induce anesthesia, the ketamine (～5.0 mg/kg for M1–M3, 8.8 mg/kg for M4) and medetomidine (～0.016 mg/kg for M1–M3, 0.053 mg/kg for M4) were injected intramuscularly (see Table). In contrast, propofol-induced anesthesia was achieved through intravenous propofol (5.2 mg/kg for M1 and M2) injection (see Table). In ketamine-induced anesthesia experiment, the ketamine (～5.1 mg/kg for M1 and M2) was injected intramuscularly (see Table). In medetomidine-induced anesthesia experiment, the medetomidine (～0.018 mg/kg for M1 and M2) was injected intramuscularly (see Table).<br />
Loss of consciousness (LOC) was defined as the point at which a monkey no longer responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab. As an additional confirmation that the monkey had achieved LOC, we could observe slow wave oscillations in the neural signal. After LOC was established, neural activity was recorded for ～25 min for the ketamine-medetomidine-induced anesthesia experiment, and ～10 min for the propofol-, ketamine-, and medetomidine-induced anesthesia experiments respectively (Anesthetized condition). Heart rate and breathing were monitored carefully throughout the length of the experiment. <br />
<br />
After LOC, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for the recovery condition. In the recovery condition, there were eyes-closed and eyes-opened conditions. The onset of eyes-closed condition in recovery condition was defined as the point at which the slow wave oscillation in the neural signal disappeared in ketamine-medetomidine- and medetomidine-induced anesthesia experiments, and the monkey started to respond to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab in propofol- and ketamine-induced anesthesia experiments.<br />
<br />
During eyes-closed condition, the monkey’s eyes were closed and the monkey sat calmly for about 15 min. Next the monkey’s eyes were opened by removing the eye-mask. During the eyes-opened condition, the monkey would sat calmly for about 15 min. <br />
<br />
We performed two to three recording sessions for each monkey, all on separate days (See Table).<br />
<br />
<br />
*;Natural Sleep Experiment<br />
<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />
<br />
EOG and EMG were performed at a sampling rate of 1 kHz by a Cerebus data acquisition system (Blackrock Microsystems, Salt Lake City, UT, USA)). EOG signals were recorded from the muscles of the right eye by placing 2 electrodes (Nihon Kohden, Disposable electrode for ECG Monitoring M-150) on near the outer and inner canthi of the right eye. The difference in potential between the 2 electrodes was then used as the EOG signal. Two electrodes were put on the chin, and the difference in the potential between these electrodes was used as the EMG signal.<br />
<br />
In the sleep condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleep condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 recording sessions were performed on separate days, respectively (See Table). The sleep state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa 2013 for the detail method).<br />

<br />
*;Anesthesia Experiments<br />
<br />
We did 4 experiments in which the monkey was under anesthesia. Two anesthetic agents, ketamine and medetomidine, were used in the first experiment. In other experiments, only propofol, ketamine or medetomidine were used respectively. <br />
<br />
During the experiments, the monkey was seated in a primate chair with both arms and head movement restricted. Neural data were acquired during the experiment. There were three conditions that were awake, anesthetized and recovery conditions. The awake condition had eyes-opened and eyes-closed conditions. At first monkey’s eyes were opened and the monkey sat calmly for up to 20 min. Next the monkey’s eyes were covered by an eye-mask to refrain from evoking visual response. During the eyes-closed condition, the monkey would sat calmly for up to 20 min at which time we would start to monitor heart rate. <br />
<br />
In experiments where the ketamine-medetomidine cocktail was used to induce anesthesia, the ketamine (～5.0 mg/kg for M1–M3, 8.8 mg/kg for M4) and medetomidine (～0.016 mg/kg for M1–M3, 0.053 mg/kg for M4) were injected intramuscularly (see Table). In contrast, propofol-induced anesthesia was achieved through intravenous propofol (5.2 mg/kg for M1 and M2) injection (see Table). In ketamine-induced anesthesia experiment, the ketamine (～5.1 mg/kg for M1 and M2) was injected intramuscularly (see Table). In medetomidine-induced anesthesia experiment, the medetomidine (～0.018 mg/kg for M1 and M2) was injected intramuscularly (see Table).<br />
Loss of consciousness (LOC) was defined as the point at which a monkey no longer responded to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab. As an additional confirmation that the monkey had achieved LOC, we could observe slow wave oscillations in the neural signal. After LOC was established, neural activity was recorded for ～25 min for the ketamine-medetomidine-induced anesthesia experiment, and ～10 min for the propofol-, ketamine-, and medetomidine-induced anesthesia experiments respectively (Anesthetized condition). Heart rate and breathing were monitored carefully throughout the length of the experiment. <br />
<br />
After LOC, the monkey recovered from anesthesia (Recovery condition). In ketamine-medetomidine- and medetomidine-induced anesthesia experiments, atipamezole which is an antagonist of medetomidine was injected intramuscularly and the monkey recovered quickly after the injection. In propofol- and ketamine-induced anesthesia experiments, the monkey was left alone for the recovery condition. In the recovery condition, there were eyes-closed and eyes-opened conditions. The onset of eyes-closed condition in recovery condition was defined as the point at which the slow wave oscillation in the neural signal disappeared in ketamine-medetomidine- and medetomidine-induced anesthesia experiments, and the monkey started to respond to manipulation of the monkey’s hand or touching of the nostril or philtrum with a cotton swab in propofol- and ketamine-induced anesthesia experiments.<br />
<br />
During eyes-closed condition, the monkey’s eyes were closed and the monkey sat calmly for about 15 min. Next the monkey’s eyes were opened by removing the eye-mask. During the eyes-opened condition, the monkey would sat calmly for about 15 min. <br />
<br />
We performed two to three recording sessions for each monkey, all on separate days (See Table).<br />
<br />
<br />
*;Natural Sleep Experiment<br />
<br />
Natural sleep experiment: During the sleep experiment under the conditions of sleep, awake with eyes closed, and awake with eyes open, the state of the monkey was monitored by recording electrooculogram (EOG) and electromyography (EMG) signals. <br />
<br />
EOG and EMG were performed at a sampling rate of 1 kHz by a Cerebus data acquisition system (Blackrock Microsystems, Salt Lake City, UT, USA)). EOG signals were recorded from the muscles of the right eye by placing 2 electrodes (Nihon Kohden, Disposable electrode for ECG Monitoring M-150) on near the outer and inner canthi of the right eye. The difference in potential between the 2 electrodes was then used as the EOG signal. Two electrodes were put on the chin, and the difference in the potential between these electrodes was used as the EMG signal.<br />
<br />
In the sleep condition, the eyes were covered by an eye mask, and the experimental room was kept quiet and dark for up to 1.5 hours. During this period, slow wave oscillation appeared intermittently in the ECoG signal. Immediately following the sleep condition, the light was turned on, and data acquisition was continued under the eyes closed condition for about 10 minutes. The eye mask was removed for the eyes open condition, which lasted for about 10 minutes. For monkeys M1 and M2, 3 and 4 recording sessions were performed on separate days, respectively (See Table). The sleep state was defined by the degree of spatial synchronization in slow wave oscillations (See Yanagawa 2013 for the detail method).<br />
