EEG Data from Alcoholic and Control Subjects

Description

Contains 64-channel electroencephalography (EEG) data from 10 alcoholic and 10 control subjects participating in a visual event-related potential (ERP) experiment. Data frame contains 5 trials (replications) from each subject. Data were recorded at 256 Hz for 1 second following the presentation of the visual stimulus.

Usage

data(eegdata)

Format

A data frame with 1638400 observations and the following 7 variables:

subject: Subject identification numbers (factor).
group: Subject group: "a" for alcoholic and "c" for control (factor).
condition: Experimental condition: "S1" (factor).
trial: Trial number for each replication (integer).
channel: Channel from which data was recorded (factor).
time: Time point at which data was recorded: 0,1,...,255 (integer).
voltage: Recorded EEG voltage in microvolts (numeric).

Details

Created from UCI MLR EEG training data using geteegdata with option nt=5.
