HCP Releases Initial MEG Dataset

The Human Connectome Project (HCP) WU-Minn consortium is pleased to announce our initial release of magnetoencephalography (MEG) data.

What’s in the HCP MEG Initial (MEG1) data release? The MEG1 data include 10 complete, high quality datasets from 14 healthy adults collected at rest (rMEG) and during 3 tasks (tMEG) that measure sensory, motor, and cognitive task performance.  For 3 subjects in this MEG release, data has already been released for the other modalities in the HCP protocol (T1w and T2w MRI, rfMRI, tfMRI, dMRI, and behavioral measures). MRI and behavioral measures for the remaining 11 subjects will be released as part of the upcoming HCP 500 Subjects Release scheduled for late spring 2014.

The MEG1 release includes:

  • raw, unprocessed MEG data in 4D Neuroimaging format
  • co-registration information (in the form of transformation matrices) that allow coordinate transformations between individual subject MEG coordinate systems and the MNI coordinate system
  • volume conduction model of the head (in MATLAB format)
  • regular 3-D source models (in MATLAB format)
  • E-Prime log files (tab-delimited and as Excel spreadsheets)
  • lists of bad channels and bad segments
  • sets of independent components (each comprising the time course and the sensor map) together with the related classification output
  • cleaned channel-level processed data aligned to stimulus and response onsets (for the task data) or segmented in short pieces (2 sec epochs for the resting state data)
  • averaged event-related fields and time-frequency estimates of power (for the task data)
  • averaged power spectra (for the resting state data)

Download MEG analysis software. Also available for download and use are pipeline scripts specifically written for analyzing HCP MEG data, collectively called “megconnectome software version 1.0”, and the FieldTrip MATLAB toolbox for MEG and EEG analysis. See for more information and to download the software.

Access MEG1 data on the HCP website. Learn about and download the HCP MEG1 dataset (~300GB of data!) via the ConnectomeDB database. Most HCP image and behavioral data is openly accessible to investigators worldwide who register and accept a limited set of Open Access Data Use Terms.

Want more information?  Check out the HCP MEG1 Data Release Reference Manual for a comprehensive guide that includes details on scanning protocols, processing pipelines, and information that will help users obtain and analyze the Q3 data.

If you are actively using HCP data and tools, we encourage you to join and be active in the hcp-users discussion group, so that you can tune in to technical discussions on issues that may be of interest.

Thanks again for your interest in the HCP.  Please send us your questions and comments anytime to

NY Times articles provide an “inside-the-scanner” look at HCP

The largest scale effort is the Human Connectome Project, involving a consortium of institutions here and abroad

Although many start their careers as scientists, it’s rare that a science reporter actually gets to participate in a scientific project. Last summer, New York Times reporter Jim Gorman got that chance, and wrote about it in two articles published today in the New York Times.

The Human Connectome Project hosted Gorman and his videographer at Washington University in St. Louis to get first hand experience with what it feels like to be a participant in the project and shoot a video about the experience.

In the article “The Brain, in Exquisite Detail”, the reporter profiles the project through conversations with HCP investigator Deanna Barch, director of the team that guides participants through the battery of in-scanner and out-of-scanner tests used for HCP. In the video, Dr. Barch explains:

What we’re doing in this project is pretty different in a couple [of] ways. We have really state-of-the-art techniques and equipment that are going to let us do this in a much finer-grained way than has ever been done before.

We’re going to be studying approximately 1,200 individuals across a wide range of things like education levels, and income levels, people from different racial and ethnic backgrounds, so we can have a much better sense of the kind of “true normal” range of brain connections …

Some of it is just basic science, trying to understand how the brain works and how the brain contributes to how we behave, but a lot of it has clinical application.

In “A Search for Self in a Brain Scan”, Gorman offers a more personal, and philosophical angle on what it is like to be scanned and, ultimately, to be able to look at images of your own brain.

Gorman was treated to several hours of MRI scanning, physical, behavioral, and cognitive tests, just as if he were one of the 1,200 participants being scanned for the HCP. Between scans, he talked with HCP investigators and research assistants about what he was experiencing, what can be learned from the data we’re collecting, and the significant effort required to process the data and make it available to the public.

A few examples of detailed brain visualizations afforded from the high resolution of the HCP MRI scans are featured, along with Jim Gorman’s journey through the scanner, in the article’s video:

UMinn HCP Investigators in the Spotlight


HCP and key consortium investigators at University of Minnesota are featured in the Fall 2013 edition of the University of Minnesota Medical School’s magazine, Medical Bulletin.

The article “Mapping the human brain” vividly describes the complexity of charting connections in the human brain, comparing the problem to drawing a road map to every living human being on Earth, 11 times over, and calling the HCP “the most ambitious brain-imaging study ever conducted”.

Detailing the vital roles HCP investigators at UMinn’s Center for Magnetic Resonance Research (CMRR) have played in advancing MRI data acquisition and analysis tools for the HCP, the article gives examples of the impact HCP data and methods are beginning to make on neuroscientific and clinical advances.

Kamil Ugurbil, Ph.D., HCP Co-PI and founder/director of CMRR, is additionally highlighted for his participation in the working group that is helping to determine the directions and nature of the research that President Obama’s  BRAIN Initiative will ultimately fund.
