Current models of the marmoset brain.

Since the availability of the common marmoset monkey as a primate model in neuroscience research has recently increased, much effort has been made to develop a reliable guide of the brain structures of this species. In this article, we review the development of the marmoset brain atlas and discuss a newly developed brain model, which was reconstructed from histological sections under volume-rendering technology. This kind of brain model allows virtual sections to be constructed on any axis, with nomenclatural annotations to structures in situ. This model is also applicable for the identification of structures revealed in magnetic resonance imaging studies. The brain model is accessible at the following web address: http://brainatlas.brain.riken.jp/marmoset/modules/xoonips/listitem.php?index_id=66.
