When clicking on the EEG and MRI download links, users will first be prompted to log on to NITRC and will need to register with the 1000 Functional Connectomes Project website on NITRC to gain access to the HBN neuroimaging datasets.

Please note that imaging data are released regardless of whether or not participants completed the remainder of the study. Therefore, some participants with imaging data may not have phenotypic data available until a future release.

Release 1.1 EEG (603 subjects) MRI (616 subjects) Phenotypic File
Release 2.1 EEG (156 subjects) MRI (159 subjects) Phenotypic File
Release 3 EEG (188 subjects) MRI (202 subjects) Phenotypic File
Release 4 EEG (359 subjects) MRI (402 subjects) Phenotypic File
Release 5 EEG (272 subjects) MRI (205 subjects) Phenotypic File
Release 6 EEG (213 subjects) MRI (174 subjects) Phenotypic File
Release 7 EEG (477 subjects) MRI (438 subjects) Phenotypic File

Phenotypic files contain the following information for each participant with imaging data:

  • Sex: 1 = Female, 0 = Male
  • Age
  • EHQ_Total: +100 = Fully Right-Handed, -100 = Fully Left-Handed
  • Commercial_Use: Did the participant consent to commercial use of data?
  • full_pheno: Does the participant have a full phenotypic file?

We provide behavioral, EEG, and eyetracking data as part of the HBN EEG dataset. In order to organize and interpret the EEG data, click below to download organizational ReadMe files that describe event triggers and behavioral data labels.

  • HBN_EEG_ReadMe.zip - Zip file containing: general ReadMe file, ReadMe file for each EEG paradigm, and a WISC Symbol Search key in both excel and .mat format.
  • EEG Channel Location File - .sfp file containing the channel location of the EEG montage.

Note: Some participants may not be able to successfully complete all components of the HBN protocol due to a variety of factors (e.g., participants experiencing claustrophobia may not be able to stay in the scanner for the full session, a participant with sensory issues may have a more limited ability to participate in the EEG protocol). To prevent data loss when possible, we include exposure procedures such as a mock MRI scanner experience during session 1, and repeat exposures to an EEG cap prior to session 4. Overall, we attempt to collect as much of the data as possible within the allotted data collection intervals and code data losses when they occur.
