Abstract The Human Connectome Project (HCP, http://humanconnectome.org) is an ambitious NIH funded project that will provide a macroscale map of human brain connectivity, together with behavioral and genetic information in 1,200 subjects constructed from non-invasive imaging modalities including functional magnetic resonance imaging (fMRI), diffusion tractography, and magneto/electro-ncephalography (M/EEG) on a subset of 100 subjects. A full understanding of brain function requires that network activity at time scales used in neural communication be mapped to the more static maps provided by anatomical and fMRI functional connectivity (fcMRI) data. A fundamental challenge lies in the linkage of these multi-dimensional dynamic networks to structural connectomes and fcMRI-derived networks. The HCP M/EEG component addresses this challenge. In my presentation I will outline the electrophysiological approach in the HCP and provide an overview of the data that will be made available, which ranges from raw unprocessed data to processed source-level data to connectivity matrices. Furthermore, I will present the specific challenges we face with the massive data processing and provide details on how we approach it using the FieldTrip MATLAB analysis toolbox.
