EEG recordings from fourteen healthy participants performing a covert spatial attention task across three sessions. The study tested real-time feedback of alpha power lateralization (α-LI) versus sham feedback in a single-blinded crossover design. It examined whether such neurofeedback leads to behavioral improvements in attention.

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.

A collection of 2,417 clinical scalp EEG recordings labeled as normal or abnormal, acquired using the standard 10-20 montage with 19 EEG channels plus 2 reference electrodes. Recordings are stored in EDF format with variable sampling rates and durations. The dataset supports EEG-based pathology detection and normal/abnormal classification.

EEG recordings from nine end-users with central nervous system tissue damage (stroke or spinal cord injury) performing five cue-guided mental tasks: word association, mental subtraction, spatial navigation, right-hand motor imagery, and feet motor imagery. Data were recorded with 30 active EEG electrodes across two sessions per participant, on different days. The dataset supports brain-computer interface research on individually adapted imagery and binary classification of mental tasks.

EEG recordings from 13 participants using a P300-based visual speller that relies on covert spatial attention and non-spatial feature attention (color and form), so users do not need to move their gaze. The study compared three speller variants (Hex-o-Spell, Cake Speller, Center Speller) in a calibration and online-test design. Data were recorded with 63 channels at 250 Hz, and event markers distinguish target from non-target intensifications.
