BNCI 2015-004 Mental tasks dataset

This EEG dataset comprises recordings from 9 individuals with central nervous system damage (stroke and spinal cord injury) performing five mental imagery tasks: word association, mental subtraction, spatial navigation, right-hand motor imagery, and feet motor imagery. Participants completed two sessions with visual cue-guided trials lasting 11 seconds each, including 7 seconds of continuous mental imagery. The dataset contains preprocessed EEG data acquired at 256 Hz from 30 electrodes using g.tec hardware, designed to support brain-computer interface research and rehabilitation applications.
