Auditory Oddball Details
There are three zip files, each contain data collected from a day, including three types of MATLAB files:
1. ECoG_ch*.mat: ECoG signals for each electrode with the sampling rate of 1000Hz.
repEvent includes the information of each tone-train (1-6 columns).
Column 1: train number
Column 2: current frequency index
Column 3: next frequency index
Column 4: SOA, repetition number
Column 5: repetition number
Column 6: time stump of train onset
Idx2Freq is a table of frequency index and actual frequency.
3. ElectrodesFr.mat: Information of the ECoG electrode locations
LINE: The outline of the marmoset brain
X: X positions of the electrodes
Y: Y positions of the electrodes
