Wang2021 – Combined SSVEP dataset with single stimulus location for two inputs

EEG Zarr

This dataset contains 32-channel EEG recordings from 8 healthy participants performing a combined steady-state visual evoked potential (SSVEP) brain-computer interface task. Spatially overlapping arrow stimuli at a single location, flickering at distinct frequencies derived from an 85 Hz CRT refresh rate, encode four directions (up, down, left, right). Participants covertly attended to one direction per trial, and the data cover three stimulation and attention schemes across two experiments.

Disentangling objects' contextual associations from perceptual and conceptual attributes using time-resolved neural decoding

EEG Zarr

Raw 128-channel EEG data from 20 observers viewing object images in a rapid presentation paradigm, together with representational dissimilarity matrices. The dataset supports time-resolved neural decoding analyses that separate objects' contextual associations from their perceptual and conceptual attributes. One participant was excluded because of a technical recording error, leaving 19 usable participants.

P-ary m-sequence-based c-VEP dataset from Martínez-Cagigal et al. (2023)

EEG Zarr

EEG dataset of a code-modulated visual evoked potential (c-VEP) brain-computer interface that uses p-ary (non-binary) m-sequences. Sixteen healthy participants were recorded with 16 EEG channels at 256 Hz. Each participant completed five conditions, stored as separate sessions, with eight runs per session (six for training, two for testing). The dataset accompanies a study of more comfortable c-VEP BCIs based on non-binary m-sequences and is distributed in BIDS format via MOABB.

HAD-MEEG

ANAT EEG MEG Zarr

HAD-MEEG is a magnetoencephalography (MEG) and electroencephalography (EEG) dataset on human action recognition. It extends the Human Action Dataset fMRI resource (HAD-fMRI) and was recorded in the same 30 participants with the same stimuli, 21,600 video clips spanning 180 categories of human action. The millisecond temporal resolution of M/EEG complements the spatial precision of fMRI, enabling spatiotemporal study of the neural mechanisms of action recognition.

NeuralEcho MACS high-density communication-related EEG dataset

EEG Zarr

High-density (127-channel) EEG recordings from 30 healthy, right-handed, native Chinese-speaking adults performing imagined and executed vocalization and writing tasks. Stimuli were four Chinese strokes (heng, shu, pie, na) and four English letters (a, b, c, d). The factorial design crossed task mode, action, script and token identity, yielding 32 event-coded conditions and 15,360 task events. The release also includes EEGLAB preprocessing derivatives and subject-level machine-learning exports.

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.
