Longitudinal EEG Test-Retest Reliability in Healthy Individuals

EEG Zarr

This dataset contains longitudinal resting-state EEG recordings from 43 healthy adults across four sessions spanning about two years, with an average inter-session interval of 7.2 months. It was collected to evaluate the test-retest reliability of EEG measures processed with an automated pipeline combining independent component analysis and wavelet-enhanced artifact removal. The data support analyses of neural components, relative power in regions of interest, and the longitudinal stability of quantitative EEG.

The Brain, Body, and Behaviour Dataset (1.0.0) - Experiment 3

BEH EEG Zarr fidelity issue

Multimodal dataset of 29 participants watching six educational videos under two conditions: an attentive session with intentional learning and subsequent factual questions, and a distracted session with a silent backward-counting task. Recordings include EEG, EOG, ECG, gaze, pupil size, blinks, saccades and head position. Questionnaires (stimulus knowledge questions and the ASRS adult ADHD checklist) are provided. The dataset supports research on attention and learning from video.

The Brain, Body, and Behaviour Dataset (1.0.0) - Experiment 2

BEH EEG Zarr fidelity issue

Multimodal dataset of 31 participants watching five short educational videos while EEG, ECG, EOG, gaze, pupil size, blinks, saccades, and head motion were recorded. Each participant completed an attentive session, in which factual questions followed each video, and a distracted session, in which they silently counted backwards. Experiment 2 uses an incidental learning design, so participants did not know in advance that they would be tested. Questionnaire data, including stimulus-related questions and the ASRS adult ADHD checklist, are included.

Healthy Brain Network (HBN) EEG - Release 5

EEG Zarr

Release 5 of the HBN-EEG dataset, the EEG component of the Child Mind Institute Healthy Brain Network, organized in BIDS format. It contains EEG recordings and behavioral responses from 330 children and adolescents (ages 5-21) performing passive tasks (resting state, surround suppression, movie watching) and active tasks (contrast change detection, sequence learning, symbol search). Events carry HED annotations, and the participants file includes psychopathology factors derived from the CBCL and basic quality-control results.

EEG, ECG and pupil data from young and older adults: rest and auditory cued reaction time tasks

EEG Zarr

This dataset contains synchronized EEG, ECG and pupil recordings from 36 young and 39 older adults performing auditory cued reaction time tasks, plus a passive listening condition. The active tasks were a cued simple reaction time task and a cued go/no-go task, and they allow investigation of age-related differences in cortical, autonomic and pupillary responses during anticipation and perceptual decision-making.

Reward biases spontaneous neural reactivation during sleep

ANAT EEG FUNC Zarr

Simultaneous EEG-fMRI dataset from 18 participants who played two games (a face game and a maze game) during wakefulness in a 3T MRI scanner. One game was randomly assigned to be won (reward) and the other lost (no reward). Participants then slept in the scanner with 64-channel EEG for 1-2 hours. A classifier trained on game-session data was applied to sleep-session fMRI to examine reward-biased spontaneous neural reactivation, and memory for both tasks was tested the next day.
