This website features a detailed, interactive connectome of a small part of the brain, currently limited to the rat. A connectome is a comprehensive description of the network elements and connections that form the brain (Sporns et al., 2005).
This website currently contains the connectome as it was created for our paper 'The anatomy of memory: an interactive overview of the parahippocampal-hippocampal network.' Nat Rev Neurosci. 2009 Apr;10(4):272-82. Select 'Connectome -> Brain connections' at the top of this page, to view the available data. We are working on an expanded version of the connectome, which will become available on this website.
We hope that sharing this comprehensive knowledge of anatomical connections in the brain will help you in your personal or professional understanding of the brain and that it will enable some to push forward the knowledge boundary towards a complete, mechanistic understanding of brain function.
