EEG data offline and online during motor imagery for standing and sitting

EEG

EEG recordings from 32 participants performing motor imagery of sit-to-stand and stand-to-sit movements, collected in offline and online brain-computer interface (BCI) phases. Signals were recorded from 17 channels (10-20 placement) at 250 Hz while visual cues on a screen guided motor imagery and idle-state trials. Offline data were used to train machine learning models that then provided real-time task detection in the online phase.

FRESH Motor Dataset

NIRS

The FRESH Motor Dataset is a functional near-infrared spectroscopy (fNIRS) dataset organized in BIDS format. It is associated with a motor task paradigm. The README gives little detail, and the record is a NEMAR-hosted version of the OpenNeuro deposit ds005963.

Multimodal dataset from the CMx7-MM Experiment

BEH EEG NIRS Zarr

A raw multimodal dataset from 30 healthy right-handed adults performing a hierarchy of cognitive, motor, and combined cognitive-motor tasks across three sessions. It includes EEG, fNIRS, ECG, EMG, Biodex torque/kinematics, push-button responses, and subjective ratings of sleepiness and cognitive load. The data are organized in BIDS and are unprocessed exports from the acquisition systems.

Motor imagination and execution with a chronic wireless epidural ECoG BCI (WIMAGINE), one participant with tetraplegia (Pollina et al. 2026)

iEEG

This dataset contains epidural electrocorticography (ECoG) recordings from a single participant with incomplete tetraplegia, implanted with the WIMAGINE wireless chronic implant over left primary motor and sensory cortex. The participant executed or imagined right-arm reaching and wrist-extension movements, either singly or simultaneously (one executed, one imagined). The release is a derivative, comprising 1-250 Hz band-pass filtered signals from 32 channels across eight sessions, with trial events and M1/S1 electrode labels. It supports study of how motor imagination and execution are decoupled in orthogonal neural representations.

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.

Cross-Environment Multi-Paradigm Motor Imagery EEG Dataset

EEG Zarr

This dataset contains EEG recordings from motor imagery (left- and right-hand) tasks collected in different recording environments. The main dataset covers 84 healthy participants in a shielded laboratory and a simulated hospital environment, and is intended to study how environmental variability affects EEG-based brain-computer interface performance. A small supplementary dataset from 3 participants recorded in a space station environment extends the collection to a non-terrestrial, microgravity setting. Multiple paradigms are included: Graz, SSMVEP-MI, and hybrid video conditions.
