EEG dataset from 25 healthy participants performing a cursor-control brain-computer interface task across five sessions. The study combined motor imagery, overt spatial attention, and simultaneous motor imagery with spatial attention (MIOSA), with online visual cursor feedback. Recordings used 64 channels at 1000 Hz, and this release provides left-hand versus right-hand motor imagery trials.

EEG recordings from healthy participants performing self-initiated palmar and lateral reach-and-grasp actions, acquired simultaneously across three recording systems: gel-based laboratory EEG, water-based mobile EEG, and dry-electrode mobile EEG. The dataset supports investigation of the feasibility of decoding natural reach-and-grasp movement-related cortical potentials across EEG acquisition modalities for brain-computer interface applications. It is distributed in BIDS format as part of the MOABB benchmark collection.

EEG recordings from 13 healthy participants performing an auditory oddball (P300) paradigm with target (1000 Hz) and non-target (500 Hz) tones at stimulus onset asynchronies between 60 and 600 ms. The study evaluated closed-loop Bayesian optimization and random search to find each individual's best stimulation speed for maximizing classification performance of a regularized LDA. The data comprise 31-channel EEG sampled at 1000 Hz, with an optimization part and a validation part.

EEG dataset recorded while participants received laser-evoked pain stimuli at fixed intensities (3/3.5 J for low pain and 3.5/4 J for high pain). Each participant completed three blocks of ten stimuli, with high and low pain intensities evenly distributed within each block. After each stimulus, participants rated pain intensity on a 0-10 scale.
