Naturalistic viewing: An open-access dataset using simultaneous EEG-fMRI

ANAT EEG FUNC Zarr

This dataset contains simultaneously recorded EEG and fMRI data from 22 adults aged 23 to 51 years, collected at the Nathan Kline Institute while participants watched naturalistic video stimuli. It also includes eye tracking, physiological (respiration) recordings, demographic information, and behavioral measures such as sleep and caffeine intake. The goal is to investigate the relationship between electrical brain activity and hemodynamic fluctuations.

Electroencephalographic responses to the number of objects in partially occluded and uncovered scenes

EEG Zarr

EEG recordings from 23 participants performing a passive viewing task with partially occluded and subsequently uncovered scenes containing game pieces on a game board. Conditions varied the number of initially visible pieces (4 or 32) and the number of pieces revealed after the occluder was removed (0 to 32). The dataset supports investigation of neural responses to object numerosity in occluded and uncovered visual scenes.

IllusionGameEEG_data

BEH EEG Zarr

This dataset contains EEG, physiological (ECG, PPG, respiration) and behavioural recordings from 103 healthy adults aged 21-45, collected in 2022-2023 as part of a larger study. Participants completed an 8-minute eyes-closed resting state, followed by the Illusion Game. In this task they made perceptual judgements about the Ebbinghaus, Müller-Lyer and Vertical-Horizontal illusions, with task difficulty and illusion strength varied. The data are intended for investigating individual sensitivity to visual illusions as a general factor.

A Multimodal Neuroimaging Dataset to Study Spatiotemporal Dynamics of Visual Processing in Humans

ANAT EEG FUNC Zarr

A multimodal neuroimaging dataset (EEG, anatomical MRI and functional MRI) for studying the spatiotemporal dynamics of visual processing in the human brain, as described by the dataset title. This is a NEMAR-hosted copy of OpenNeuro dataset ds002814. The associated article was under review at the time of the record. The source README is an unfilled placeholder, so further study details are not available in the dataset documentation. Contact the corresponding authors (Seyed-Mahdi Khaligh-Razavi, Fatemeh Ebrahiminia) for more information.

MEG Zarr

An MEG dataset recorded while participants viewed colored square wave spiral gratings and the color words "blue" and "green". Eight spiral gratings (pink, blue, green, and orange, each in light and dark variants) subtended 10 degrees of visual angle, and the words appeared in white on a gray background. Each stimulus was presented for 116 ms, and event triggers identify the stimulus category. The data are suited to studying neural representations of color and color words.

Eye-BCI Motor Execution dataset from Guttmann-Flury et al 2025

EEG Zarr

A BIDS-formatted EEG dataset of two-class hand-grasping motor tasks (left vs. right hand) from 31 healthy participants, recorded with a 64-channel Neuroscan system at 1000 Hz across up to three sessions of 40 trials each. It is a derivative of the multi-paradigm Eye-BCI dataset, which combines EEG, eye-tracking and high-speed video for ocular activity analysis. It is provided through MOABB for benchmarking motor-related brain-computer interface decoding.

Rapid coordination of effective learning by the human hippocampus: intracranial EEG during scene recognition with eye tracking

iEEG

Stereo-EEG recordings from six patients with medically refractory epilepsy performing a scene recognition memory task with concurrent EyeLink eye tracking. The dataset accompanies a study of how the human hippocampus rapidly coordinates effective learning, and is a lossless iEEG-BIDS re-packaging of the authors' public Zenodo release. It includes electrode MNI coordinates, behavioural arrays, eye-tracking files and the authors' analysis code in sourcedata.
