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

Monkey Qu: 20120417, 20120423, 20120424, 20120426

Monkey Bt: 20130708, 20130710, 20130718, 20130723, 20130725, 20130731

Monkey Cn: 20140612, 20140613, 20140616

- Data format

Three types of the mat-files were uploaded for each monkey.

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)).

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).

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))
