EEG, pupillometry, ECG and photoplethysmography, and behavioral data in the digit span task and rest

BEH EEG Zarr

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.

A dataset recorded during development of an affective brain-computer music interface: calibration session

EEG

EEG, galvanic skin response (GSR) and electrocardiogram (ECG) recordings from healthy adult volunteers listening to 40-s synthetic music clips designed to target specific affective states defined by valence and arousal. The data were collected to calibrate an affective brain-computer music interface that induces target emotional states through real-time modification of generated music. Each session comprised 5 runs of 18 music trials, and self-reported valence and arousal ratings are included. This is the calibration dataset of three related datasets from the BCMI-MIdAS project.

WIRED ICM Sample Dataset - Workshop on Intracranial Recordings in Humans, Epilepsy, DBS

ANAT iEEG Zarr

A sample intracranial EEG (iEEG) dataset prepared for the WIRED ICM course on intracranial recordings in humans, epilepsy, and deep brain stimulation (Paris, March 2024). It contains recordings from patients with epilepsy during naturalistic listening tasks (movie trailers and TIMIT sentences). It also includes illustrative examples of seizure-related activity and vagus nerve stimulator artifact.

Thapa2025: Freewill reach-and-grasp motor-execution dataset from Thapa et al. 2025

EEG

A multichannel EEG dataset of self-paced (freewill) reach-and-grasp movements recorded from 23 healthy right-handed participants across 49 sessions. On each of 6808 trials the participant freely chose one of four cups, two filled with water and two empty, and decided when to move. Recordings were made at 250 Hz with a 31-channel scalp EEG montage plus EOG and auxiliary channels, to support brain-machine interface research on natural motor execution.

Qin2023 action observation ECoG: re-referenced region-of-interest electrocorticography during observation of predictable and unpredictable action movies

iEEG

Continuous electrocorticography (ECoG) from 10 epilepsy patients (8.70 h total, 1000 Hz) recorded while they watched movies of sequential actions with predictable and unpredictable camera changes. The derivative release contains re-referenced region-of-interest channels converted to BrainVision format, with camera-change events, ACPC and MNI electrode positions, and the stimulus movies and annotations. It supports analysis of predictive coding and information flow in beta and gamma activity during action observation.

Eye-BCI Motor Execution dataset from Guttmann-Flury et al 2025

EEG Zarr

A BIDS-formatted EEG dataset of two-class hand-grasping motor tasks (left vs. right hand) from 31 healthy participants, recorded with a 64-channel Neuroscan system at 1000 Hz across up to three sessions of 40 trials each. It is a derivative of the multi-paradigm Eye-BCI dataset, which combines EEG, eye-tracking and high-speed video for ocular activity analysis. It is provided through MOABB for benchmarking motor-related brain-computer interface decoding.
