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.

An example intracranial EEG recording from a single epilepsy patient under intracranial monitoring, comprising 61 channels sampled at 5000 Hz for 10 minutes. It includes 357 automated qHFO (quantitative high-frequency oscillation) detections with start/stop samples and channel indices. The data demonstrate a wavelet-entropy feature that separates EMG-contaminated false HFOs from true HFOs, as described in Ren et al. (2019).

This dataset contains EEG recordings collected to study how expectation affects repetition suppression in nociception. It supports investigation of how the brain's responses to repeated painful stimuli are modulated by predictions about those stimuli. The data are organized in BIDS format.

The I-CARE database contains continuous EEG and, where available, ECG recordings from comatose adults after cardiac arrest, collected at five academic hospitals in the United States, the Netherlands and Belgium. It includes baseline clinical variables and dichotomised Cerebral Performance Category outcomes to support neurological prognostication. This BIDS conversion covers the PhysioNet release 2.1: 607 patients and 36,123 hourly recordings, which served as the training set for the George B. Moody PhysioNet Challenge 2023.

EEG recordings from 33 participants who each completed both a visual and an auditory surprise task, with task order counterbalanced. The dataset supports investigation of electrophysiological markers of surprise-induced failures of visual and auditory awareness. Data from participants excluded at various analysis stages are included up to the stage of processing they reached.

Preprocessed intracranial EEG recordings of cortico-cortical evoked potentials (CCEPs) from orbitofrontal cortex electrodes in 7 patients. Single-pulse electrical stimulation was used to map effective connectivity between orbitofrontal subregions, including homotopic communication across hemispheres. The derivative release provides unreferenced and bipolar-referenced per-electrode timeseries at 1000 Hz, stimulation events, and sulcus-relative electrode locations.

This dataset contains non-invasive electrophysiological recordings from the human cervical spinal cord in 30 healthy young adults, collected to test whether temporal expectation influences initial sensory processing in the spinal cord. Participants received electric median nerve stimulation at the left wrist after an auditory cue, with the cue-stimulus interval either fixed at 1100 ms or varied randomly between 100 and 2100 ms. Participants silently counted rare double-stimulus trials (80 ms ISI) and reported the count at the end of each block.

EEG recordings from 15 healthy participants performing a visual P300 oddball task while walking on a treadmill at 1.6 m/s, released as BCI Competition 2020 Track 5. The dataset combines 46-channel scalp EEG, 14-channel ear-EEG, 4 EOG channels, and 6 inertial measurement unit channels sampled at 100 Hz. It is intended for evaluating brain-computer interface performance under ambulatory conditions, with trials divided temporally into training, validation, and test sets.

This dataset contains synchronized EEG, autonomic physiological recordings, and behavioral responses collected during an emotional word association task centered on fear-related concepts. Participants either selected suggested words or generated new ones. Eight-channel EEG, electrodermal activity, blood volume pulse, interbeat interval, skin temperature, and word events with semantic similarity scores between consecutive words are included.

A derivative BIDS-iEEG repackaging of the processed 'stim-seizures' release from the Hospital of the University of Pennsylvania and the Children's Hospital of Philadelphia. It includes clinician-marked and LSTM-model seizure annotations, electrode localisations with atlas labels, and four preprocessed bipolar SEEG seizure traces (spontaneous and low-frequency stimulation-induced). It contains no raw iEEG recordings. The data support analyses of whether 1 Hz electrical stimulation can replace spontaneous seizures and of the seizure-generating networks.
