BigP3BCI Study M — 9x8 adaptive/checkerboard (21 ALS subjects)
EEG ZarrThis dataset is a BIDS-formatted derivative of Study M from the bigP3BCI collection, a large open P300-based brain-computer interface resource. It contains 16-channel EEG recorded at 256 Hz from 21 participants using a 9x8 character speller grid with adaptive and checkerboard stimulus paradigms. Target and non-target events are annotated with HED tags, supporting machine-learning work on P300 speller classification.

Dreyer et al. 2023 — A large EEG database with users' profile information for motor imagery brain-computer interface research
EEG ZarrA large EEG database from 87 healthy participants recorded during a single-day motor imagery brain-computer interface (BCI) experiment. The data are organized into three datasets (A, B, C) that share one Graz-protocol task, left- versus right-hand motor imagery, with 240 trials per participant (over 20,800 trials in total). It also provides demographic, personality and cognitive-trait information, which supports studies of how user profiles relate to BCI performance and cross-user classification algorithms.

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

142 by Biosemi
EEG ZarrEEG recordings from 142 participants who received laser-evoked pain stimuli at fixed low and high intensities and rated the pain intensity after each stimulus. Each participant completed 3 blocks of 10 stimuli, with high and low pain stimuli evenly distributed within each block. Data were recorded with a Biosemi system and are intended for studying the neural correlates of pain perception.
