This dataset comprises simultaneous EEG and eye-tracking recordings from 21 healthy participants performing a matrix-based brain-computer interface spelling task. EEG data were acquired using a 24-channel dry electrode system at 300 Hz, while eye movements were recorded at 60 Hz using a portable eye tracker. The dataset includes calibration and copy spelling tasks with single-character-presentation visual paradigm, providing multimodal sensor fusion data for investigating EEG-based BCI typing systems.

This dataset comprises fMRI and EEG recordings from 69 participants investigating the role of rapid eye movement (REM) sleep in neural differentiation of memories within the hippocampus. Participants completed three fMRI scans and one EEG session, with the EEG session containing either sleep data from a nap or quiet wake recordings depending on experimental condition. The study examines how sleep-dependent processes contribute to memory consolidation and neural representation in the hippocampus.

This dataset comprises continuous EEG recordings from 12 subjects during a visual attention task, originally published by Gramann et al. (2010) to investigate dimension-based attention modulation of early visual processing. The dataset includes 64-channel scalp EEG data with pre-computed ICA decomposition and expert-annotated independent component labels, providing a resource for studying automatic component classification and visual attention mechanisms. The original data was subsequently used by Frølich et al. (2015) to investigate automatic labeling of independent components in ICA. Data was converted to BIDS format by Austin J. Brockmeier and Carlos H. Mendoza-Cardenas with permission from Klaus Gramann, following a data copy provided by Laura Frølich.

This dataset contains raw electroencephalography (EEG) recordings collected during a social observation task. Participants viewed videos of social interactions while EEG was recorded. The dataset is organized according to the Brain Imaging Data Structure (BIDS) standard and includes EEG data from participants performing a passive social observation paradigm. This resource provides neurophysiological measurements suitable for investigating neural correlates of social perception, action observation, and interpersonal understanding. The dataset includes continuous EEG recordings, event markers for stimulus presentation, and participant demographic information. For complete technical details regarding electrode configuration, sampling rate, filter settings, and number of participants, please refer to the README.md file and dataset_description.json.

This dataset comprises intracranial EEG recordings from 23 patients with drug-resistant epilepsy undergoing stereo-EEG presurgical evaluation. The dataset includes 41 high-frequency stimulation events that evoked negative motor responses, with 24-second iEEG recordings per stimulation event (9-10 seconds pre-stimulation, up to 5 seconds stimulation, and 9-10 seconds post-stimulation). Stimulation parameters, contact pairs, current intensities, and evoked effects are documented in event files, enabling analysis of cortical responses to electrical stimulation.

This longitudinal neuroimaging study investigates neural mechanisms of motor skill learning, consolidation, and retention using magnetoencephalography (MEG) combined with structural MRI. Thirty-one healthy right-handed adults performed a sequential finger-tapping task during an initial training session followed by retest sessions at approximately 24 hours and 30 days post-training. The dataset includes continuous MEG recordings, high-resolution anatomical MRI, behavioral performance metrics, eye-tracking, pupillometry, and electromyography data synchronized across all sessions.

This dataset comprises electroencephalography (EEG) recordings from young adult participants during resting state and auditory oddball task conditions. Data were collected under two experimental conditions: a control condition and a shock threat condition involving threat of unpredictable shock. The dataset includes both passive and active variants of the auditory oddball task, as well as resting state recordings with eyes open and closed, designed to investigate locus coeruleus-noradrenaline system function and its relationship to attention and arousal.

MEG-SCANS is a comprehensive magnetoencephalography dataset comprising raw and MaxFiltered recordings from 24 German-speaking participants engaged in auditory experiments. The dataset includes approximately one hour of stimuli per participant consisting of audiobooks, sentences from the Oldenburger Matrix Sentence Test at varying intelligibility levels for speech reception threshold assessment, and chirp stimuli for signal quality evaluation. Each participant's data includes raw and processed MEG recordings, empty-room recordings, structural MRI, behavioral audiograms, and corresponding audio stimulus materials, organized according to BIDS standards to facilitate large-scale encoding/decoding analyses of neural responses to speech.
