Additional Information for "Visual Grating Task"
Q) Do the values in 'Ain' mean anything besides event? (ex. 1652 and 1653 in Stimulus4 are same or different?)[edit]
A) Because of noise, the amplitude of signal was fluctuated.
1652 and 1653 in Stimulus4 were same (the all values in 1600-1700 belonged to Stimulus4).
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.)[edit]
A) Display resolution: 1920×1200
Display Size: 518.4×324.0mm
Spatial frequency: 0.01cycle/pixel
The interval of grating: 27mm
Time frequency: 4Hz
Moving velocity: 108 mm/sec
Q) Do the angles (0,0) correspond to the center of the visual stimulus?[edit]
A) Yes. To be more precise, it corresponds to the center of the movie. In the experiment, I tried to match the center of the movie with the center of the stimuli.
