Over the next 3 years (2012-2015), the Human Connectome Project (HCP) is scanning 1,200 healthy adult subjects on the same MRI scanner using the same protocol for every subject. We began our planned quarterly releases of data with the Q1 release (March 2013) and are continuing with the current Q3 release. Our goal is to map region-to-region structural and functional connections of the human brain: the "human connectome."
The Q3 data release consists of multimodal MRI data collected from more than 85 healthy young adults scanned in Spring 2013. The current release expands the total (Q1-Q3) number of released healthy participant data for imaging and/or behavioral measures to more than 220. The Q3 release also includes:
Our target number is 1,200 healthy adults, ages 22-35 (~100 scanned/quarter), whose race/ethnicity is representative of the US population. We are recruiting twins and their non-twin siblings in order to enable research on the variability and heritability of brain structure and connectivity.
HCP datasets are collected from each participant during a 2 day visit to Washington University that includes a demographic survey, behavioral tests, and up to 5 MRI scan sessions that include structural, functional (resting state and task) and diffusion imaging. We follow a Standard Operating Procedure for data collection and use the same Imaging Protocols for every participant.
Several types of data are available in this release:
The high-resolution image data collected on each HCP subject results in file sizes that are quite large (10-18 GB/subject; all subjects ~ 6 TB). Therefore, if you choose to obtain HCP data via download, you should be prepared to experience long download times and to devote an appropriately large amount of disk space to housing the data.
We recommend that groups of users at the same institution organize themselves to obtain a single copy of HCP data for local distribution (via joint purchase of "Connectome in a Box" or a single download).
How to access HCP Data:
Acceptance of HCP Open Access Data Use Terms is required for access to all HCP image and behavioral data. Users will be prompted to accept the Data Use Terms upon initial login for data access.
Access to potentially identifying and/or sensitive data such as subject age, ethnicity, substance abuse and other specific measures is restricted. Investigators who intend on using this data for their research must complete and return an application that includes the HCP Restricted Data Use Terms.
