EEG dataset from the PROTEUS brain-computer interface (BCI) project in Bordeaux, released for the EEG/EMG Foundation Challenge 2026 (Track 02). It contains recordings from 10 participants across 14 sessions (112 runs) performing three cued mental tasks: kinesthetic motor imagery, mental subtraction and word generation. Runs include resting baselines, calibration runs with sham feedback and online runs with real feedback, using Graz and BrainHero interfaces.

EEG dataset investigating the sense of agency over movements produced by electrical muscle stimulation (electrically-actuated movements). It examines the illusion of agency when involuntary, externally actuated movements are experienced, and provides raw EEG recordings organized in BIDS format.

EEG recordings from 12 healthy participants performing three-class motor imagery of the same upper extremity: rest, hand grasping, and elbow flexion. Each participant completed 4 sessions of 20 trials per class, recorded with a 32-channel EGI HydroCel net at 1000 Hz. The dataset supports research on brain-computer interface classification of imagined movements within one limb, for example for rehabilitation and motor control.

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.

EEG recordings from 15 healthy participants performing a P300-based brain-computer interface task for controlling a home appliance, specifically a door lock. Data were acquired with 31 active EEG channels at 500 Hz during a four-class visual oddball paradigm presented on an LCD display, with target and non-target flashes. Each subject completed 50 training and 30 testing blocks, including online testing with visual feedback.
