Overview
The Healthy Brain Network EEG Datasets (HBN-EEG) is a curated collection of high-resolution EEG data from over 2,600 participants aged 5-21 years, contributed by the Child Mind Institute Healthy Brain Network (HBN) project.
Currently, HBN-EEG includes 9 dataset releases in the Brain Imaging Data Structure (BIDS) format, containing EEG and behavioral data from different subjects performing the same tasks. Further dataset releases will be added as the study progresses.
These datasets also contain rich task-event annotations using Hierarchical Event Descriptors (HED) , making them ideal for large-scale analyses and machine-learning inference related to child and adolescent mental health, including advanced meta and mega analyses. Future enhancements will include more data layers such as eye-tracking and personalized EEG features.
Data Description
Contents
- EEG Data: EEG recordings from a set of participants performing multiple tasks (some passive, some task-based with behavioral input).
- Behavioral Responses: Reaction times and accuracy are integrated with EEG events for streamlined analysis in
_events.tsv
files.
Special Features
- Hierarchical Event Descriptors (HED): Each dataset release is annotated using HED tags for comprehensive and consistent cross-study analyses.
- Psychological Metrics: The datasets include psychometric bi-factors (p-factor, internalizing, externalizing tendencies) derived from questionnaires to provide insights into physiological and psychological data.
Platform Updates & Future Features
- Personalized Electrode Locations: Future dataset releases will include more precise electrode location files tailored to each participant’s head anatomy.
- Eye-Tracking Data: Upcoming additions will include synchronized eye-tracking data to provide a better understanding of attention and visual behaviors during EEG tasks.
- Lead Field Matrix: Plans include releasing customized lead-field matrices for source imaging analyses.
Number of subjects across releases
Number of subjects with available EEG data runs across HBN-EEG Releases. “Available” flags are determined based on data length, sampling frequency, and availability of event markers (see the HBN-EEG preprint for more details).
