!! Note that, for "Passive viewing task", the data has already merged across days!!

"Exp date" refers to the date we uploaded the data for Neurotycho. The dates we conducted the experiments were as below.


Monkey Qu: 20120502, 20120507, 20120508, 20120509, 20120510, 20120514, 20120515

"Exp date" refers to the date we uploaded the data for Neurotycho. The dates we conducted the experiments were as below.


Monkey Qu: 20120502, 20120507, 20120508, 20120509, 20120510, 20120514, 20120515

B "info.mat" contains "prms" (struct), "tmpCategory" (cell) and "eyeData" (cell). "prms" is the time-stamps of the events and the task parameters in each trial (see below i) for the details). "tmpCategory" refers to what kind of images we presented (see below ii) for the detail). "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).

i) Description of the events & parameters in each trial, and their field names

fixStart: the time of the fixation start

rewOn: the time of the reward delivery

vstimOn: the time of a static-image onset

vstimType: the category of the static image presented, 1-10 (see ii)


ii) Categories of the static images We used the images of 10 categories and "tmpCategory" refers to their category names.

tmpCategory ={'beermug','cartie','flower','fruit','humanface','humanfeese','chim', 'macaca', 'otter', 'snake'}


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;

load('elPosition_Qu.mat');

figure, imagesc(IMG), axis equal, axis off, hold on, plot(elX,elY,'ko'),

for iCh =1:length(elX)

text(elX(iCh), elY(iCh), sprintf('%d',iCh))

end
