EEG recordings from 20 participants performing an internal attention task with eyes closed. Participants followed automated verbal instructions to relax, get ready, and mentally concentrate on a target for roughly 15-second periods. The sequence of relax, get-ready, and concentrate phases was repeated 20 times per participant.

Raw 64-channel EEG, electrocardiography, photoplethysmography, pupillometry and behavioral data from 86 participants during 4 minutes of eyes-closed rest and a digit span serial recall task. Participants memorized or passively listened to auditory digit sequences of 5, 9, or 13 items. The dataset supports work on cognitive load discrimination, event-related and oscillatory dynamics during encoding and maintenance, and links between working memory, central and peripheral physiology.
This dataset contains 1,983 overnight polysomnography recordings from patients at the Massachusetts General Hospital sleep laboratory, most of whom were evaluated for suspected sleep disorders such as obstructive sleep apnea. It was created for the PhysioNet/Computing in Cardiology Challenge 2018 on automatic detection of sleep arousals. The training set (994 subjects) includes expert annotations of sleep stages, respiratory events and arousals, while the test set (989 subjects) contains signals only. Recordings comprise EEG, EOG, EMG, respiratory effort, airflow, SpO2 and ECG channels sampled at 200 Hz.
