Scrapers are categories by language – PHP, Python and Ruby – and the site is currently in beta.
The Human Connectome Project aims to provide an unparalleled compilation of neural data, an interface to graphically navigate this data and the opportunity to achieve never before realized conclusions about the living human brain.
