EEG recordings from 13 healthy participants performing a copy-spelling task with a visual 6x7 matrix ERP speller. The speller was designed for learning from label proportions (LLP), an unsupervised, calibrationless classification approach for ERP-based brain-computer interfaces. Two stimulus sequences with different target/non-target ratios allowed LLP to reconstruct mean target and non-target responses without labeled data. In the original online study, 84.5% of characters were spelled correctly on average without prior calibration.

EEG recordings from 12 healthy participants performing an offline 4-class reactive BCI task based on code-modulated visual evoked potentials (c-VEP). The dataset covers the 'Burst c-VEP' condition at 40% amplitude depth, in which short bursts of aperiodic flashes are presented at 2-4 flashes per second. It supports work on stimulus design, visual comfort, and CNN-based bitwise decoding with minimal calibration data.
A code-modulated visual evoked potential (c-VEP) brain-computer interface dataset recorded from 30 healthy participants using 8 EEG electrodes at 512 Hz. Participants fixated on target cells in a 20-symbol grid while all cells flashed pseudo-random modulated Gold codes. The data support comparison of full-calibration, reduced-training and zero-training classification using a reconvolution encoding model.

EEG recordings from 12 healthy participants performing an offline 4-class code-modulated visual evoked potential (c-VEP) reactive BCI task. This subset contains the m-sequence condition at 40% amplitude depth, from a factorial study that compared burst and m-sequence codes at 100% and 40% modulation depth. The dataset supports evaluation of CNN-based decoding with minimal calibration data and of the visual comfort of reduced-intensity stimuli.

This dataset contains EEG recordings from phoneme discrimination tasks combined with transcranial magnetic stimulation (TMS) of the motor cortex. It merges two studies: a 2019 study of consonant-vowel and vowel-consonant pairs in 8 participants, and a 2021 study in 16 participants that added single phonemes, real words and pseudowords. It is intended to support research on speech decoding and the role of articulation and coarticulation in speech perception.
