Participants
132 participants (Age mean:24.0 SD:5.0)
Among them, 32 participants went for the follow-up second recording.
Participants sat at rest with their eyes closed.
The EEG signals were recorded for 180 s using an EEG amplifier (BrainAmp MR+, Brain
Products GmbH, Gilching, Germany) and a 63-channel EEG cap (Easycap, EASYCAP
GmbH, Herrsching, Germany) placed on the scalp in accordance with the International
10/10 system.
The following recording configuration was used.
Recording reference: left earlobe reference
The ground electrode: AFz
Sampling frequency: 1000 Hz
low-cut frequency: 0.016 Hz
high-cut frequency: 250 Hz
Offline re-reference: the average potentials of the left and right earlobes.
Format: matlab mat files (Zip compressed).
The autism-spectrum quotient (AQ) subscales were acquired from 88 participants
after the EEG recording.
See "Information_on_participants.xlsx" for participants' details.
Matlab code for the analysis is available as "MSCA-Toolbox-main.zip".
"Easycap63.locs" is an electrode location file in the EEGLAB polar coordinate .locs format.
