Spectacular MRI Brain Imagery from HCP

From the Human Connectome Project Gallery

Posted for no better reason than that they're so beautiful, and for what they reveal about our orderly and symmetrical cerebral wiring...

Mapping of the human connectome offers a unique opportunity to understand the complete details of neural connectivity (Sporns et al., 2005, Wedeen et al., 2008, Hagmann et al., 2007). The Human Connectome Project (HCP) is a project to construct a map of the complete structural and functional neural connections in vivo, within and across individuals.

The HCP represents the first large-scale attempt to collect and share data of a scope and detail sufficient to begin the process of addressing deeply fundamental questions about human connectional anatomy and variation.

A collaboration between Massachusetts General Hospital and UCLA, the HCP is being developed to employ advanced neuroimaging methods, and to construct an extensive informatics infrastructure to link these data and connectivity models to detailed phenomic and genomic data, building upon multidisciplinary, collaborative efforts currently underway.

Working with other HCP partners based at Washington University in St. Louis, the group will provide rich data, essential imaging protocols and sophisticated connectivity analysis tools for the neuroscience community.



White Matter Fibers Harvard Dataset

White matter fiber architecture of the brain. Measured from diffusion spectral imaging (DSI). The fibers are color-coded by direction: red = left-right, green = anterior-posterior, blue = through brain stem.
