The Mouse Atlas Project (MAP) aims to develop a dynamic, probabilistic atlas of the adult and developing C57BL/6J mouse.

The framework, in the form of a digital atlas of the C57BL/6J mouse brain, is composed of volumes of data acquired from uMRI, blockface imaging, histology, and immunohistochemistry and a set of visualization, database, mapping and measurement tools. Users can import their own data into the atlas and use the same tools to visualize, compare and measure domains of gene expression in normal, gene-targeted knock-out, or transgenic mice.
