Dataset of intracranial EEG, scalp EEG and beamforming sources from epilepsy patients performing a verbal working memory task

EEG iEEG Zarr

This dataset contains simultaneously recorded scalp EEG and intracranial EEG (depth electrodes) from fifteen epilepsy patients undergoing intracranial monitoring while performing a modified Sternberg verbal working memory task. Encoding, maintenance, and recall are temporally separated. It includes electrode MNI coordinates with anatomical labels, trial-level behavioral information, and LCMV beamforming-reconstructed virtual sensor data for several cortical regions. The data support studies of working memory, connectivity, and replay of memory items.

Farabbi2020: Motor-Imagery EEG dataset during robot-arm control

EEG

Motor-imagery EEG recorded from 12 healthy, BCI-naive participants performing cued left- versus right-hand imagery to control a Baxter robot arm reaching toward objects. Each participant completed three sessions with first-person and third-person visual feedback conditions, giving 480 trials per subject. Data were recorded with a 32-channel LiveAmp system at 250 Hz and re-released in BIDS format via MOABB.

A dataset recorded during development of an affective brain-computer music interface: training sessions

EEG

EEG, galvanic skin response (GSR) and electrocardiogram (ECG) recordings from 16 healthy participants who listened to 40 s synthetically generated music clips targeting two affective states defined by valence and arousal. Data were collected over three sessions on separate days, each with four runs of 18 trials. The recordings were made to train an affective brain-computer music interface (BCMI-MIdAS) to induce target emotional states in individual users. Self-reported valence and arousal values and auxiliary variables are included.

Checkerboard m-sequence-based c-VEP dataset from

EEG Zarr

An EEG dataset of code-modulated visual evoked potentials (c-VEP) elicited by checkerboard-pattern m-sequence stimuli, recorded from 16 healthy participants with 16 channels at 256 Hz. It was collected to evaluate how the spatial frequency of visual stimuli affects the performance and user experience of c-VEP-based brain-computer interfaces. Each stimulus condition is stored as a separate session, with three runs per session (two for training, one for testing). The data are distributed in BIDS format via MOABB.

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.
