This year’s OHBM conference comes at a time when our project is in the middle of an exciting transition. We are preparing to begin Phase II of the project, in which we collect scan data from 1,200 human subjects, and will soon release Phase 1 Pilot Data for the scientific community at large. In addition, we have an early release of a powerful open-source software tool to debut: Connectome Workbench, which allows users to explore connections in the brain in three dimensions.
Here is a rundown of the HCP presence at this year’s Human Brain Mapping conference.
Educational Course: “The Connectome”
HCP investigator Heidi Johansen-Berg (Oxford University) co-led a comprehensive two-part course on building and data-mining the connectome. Additionally, HCP investigators David Van Essen and Mark Woolrich lectured on key components. According to the course curriculum, attendees learned to:
- Understand methods for acquisition and analysis of diffusion MRI, resting state FMRI, EEG and MEG data;
- Understand network modelling methods for connectomics;
- Give examples of approaches to visualising connectomes; and
- Give examples of applications of connectomics to understanding brain function and dysfunction.
Educational Course: “Imaging Genetics”
HCP investigator Thomas Nichols (University of Warwick) co-led a course on the emerging realm of imaging genetics for OHBM 2012 attendees. With a cohort of 1,200 subjects made up of twin and non-twin siblings, the combined imaging and genetic data assembled Human Connectome Project will provide a trove for future analysis. According to the course prospectus, attendees learned to:
- Understand the fundamentals of the molecular basis of genetic variation, and how that variation is modeled in traditional genetics studies.
- Understand the difference between linkage, association and heritability analyses.
- Understand the relative strengths & weaknesses of each different type of brain imaging phenotype used to find genetic association.
- Understand how imaging genetics can be applied to areas like schizophrenia or Williams’s syndrome.

In addition to these two full courses, there were ample opportunities to be enlightened on connectome-related topics.
