My Virtual Dream - EEG data - Oct 5-6, 2013

Data from My Virtual Dream installation Oct 5-6, 2013.

Research article with full description of the data : TBA

Data are organized in subject-specific matlab files, according to session number (1-29), pod number (1-4) and player number (1-5). Entire experiment was performed in 29 sessions, from 7pm, Oct 5, 2013 to 6:30am Oct 6, 2013. During each session there were 20 subjects, divided into 4 pods of 5 subjects. Only complete, partially preprocessed, data sets are included. For each subject, condition specific EEG time series were extracted and resampled to 256Hz.

Subject's .mat file contains the following variables:

session -- number -- session number (1-29), the same as in the filename

pod -- number -- pod number (1-4).

position -- number -- subject's position within pod (1-5, sitting arrangement from left to right)

age -- number -- subject's age in years

sex -- string -- 'f' or 'm'

srate -- number -- sampling rate is the same for all subjects: 256Hz

chan_names -- cell array of strings -- names of 4 EEG channels, given in the same order as EEG data

conditions -- cell array of strings -- names of conditions

cond_eeg -- cell array of 2D matrices -- conditition specific EEG data in (time x channel) format

aP -- 1D array -- condition specific aP performance measure (number of a+ states divided by number of a- states during first 20 seconds of the condition)

bP -- 1D array -- condition specific bP performance measure (number of b+ states divided by number of b- states during first 20 seconds of the condition)
