BCI speller task - EEG data

EEG data (eeg_wordX, v1) from 10 autistic and 10 non-autistic individuals who performed a pseudoword reverse spelling task using a BCI speller. It also includes task-event timings (eeg_events_wordX, v1), a channel locations file (v2), behavioural outputs (v2), and participant information (age and gender, v3).

Details about the dataset:

Groups:
S - Non-autistic
P - Autistic

Each word of each participant has 2 matrixes: eeg_word (with the eeg data values) and eeg_events (with the protocol/events).

eeg_word:

channels x time, srate = 256 Hz
