MEGMEM
MEG Zarr
[ collected to test whether intrinsic brain spatio-temporal dynamics, measured as EEG microstates, relate to executive functions. Session 1 contains 5 minutes of alternating eyes-closed and eyes-open rest recorded with a 64-channel BioSemi system. Session 2 contains behavioral data from nine executive function tasks. The dataset supports correlating microstate metrics with mean z-scored executive function performance.

Chen2017 – Single-flicker online SSVEP BCI dataset
EEG ZarrThis dataset contains 32-channel EEG recorded with a BioSemi ActiveTwo system from 12 healthy participants using a single-flicker, spatially coded SSVEP brain-computer interface for spatial navigation. A single 15 Hz flickering square is shown at the screen center, and four non-flickering targets lie at the cardinal directions. Gaze direction produces distinct spatial topographies of the SSVEP response. Two sessions per subject are included: a structured training calibration session and an online adaptive BCI game session.

PoloHortiguela2025: Motor imagery of ankle dorsiflexion/plantarflexion dataset
EEGOpen-loop EEG dataset of kinesthetic motor imagery of ankle dorsiflexion/plantarflexion alternated with relaxation, recorded from six healthy participants. Each participant completed two sessions, one with a static and one with a moving lower-limb exoskeleton. The recordings contain 28 EEG channels and 4 EOG channels sampled at 250 Hz. This is a BIDS re-release of the Zenodo deposit, produced via MOABB.

Human electroencephalography recordings from 50 subjects for 22,248 images from 1,854 object concepts
EEG ZarrElectroencephalography recordings from 50 participants viewing 22,248 images spanning 1,854 object concepts from the THINGS database. Images were shown in rapid serial visual presentation streams at 10 Hz while participants performed an orthogonal fixation colour change detection task. The dataset supports research on the temporal dynamics of object recognition and visual representation in the human brain.
