Session_28_pod_03_player_02.mat

Data from My Virtual Dream installation Oct5-6, 2013.
Data are organized in subject-specific matlab files, according to session number (1-29), pod number (1-4) and player number (1-5). Only complete data sets are included. These data are partially preprocessed: for each subject, we extracted condition specific EEG time series resampled to 256Hz. Each .mat file contains the following fields:
<strong>session</strong> -- number -- session number (1-29), the same asin the filename.Data were acquired in 29 sessions,from7pm to 7 am.
<strong>pod</strong> -- number -- pod number (1-4). During each session there were 20 subjects, divided into4 pods of 5.
<strong>position</strong> -- number -- position within pod (1-5, sitting arnagement from left to right)
<strong>age</strong> -- number -- subject's age in years
<strong>sex</strong> -- string -- 'f' or 'm'
<strong>srate</strong> -- number -- sampling rate is the sme for all subjects: 256Hz
<strong>chan_names</strong> -- cell array of strings -- names of 4 channels given in the same order as EEG data
<strong>conditions</strong> -- cell array of strings -- names of conditions
<strong>cond_eeg</strong> -- cell array of 2D matrices -- conditition specific EEG data in time x channel format
<strong>aP</strong> -- 1D array -- condition specific aP performance measure (number of a+ states divided by number of a- states during first 20 seconds of the condition)
<strong>bP</strong> -- 1D array -- condition specific bP performance measure (number of b+ states divided by number of b- states during first 20 seconds of the condition)
