Our goal is to develop automated methods to relate spatial variation in gene expression to anatomy. We want to find marker genes for specific anatomical regions, and also to draw new anatomical maps based on gene expression patterns. We will validate these methods by applying them to 46 anatomical areas within the cerebral cortex, using the Allen Mouse Brain Atlas coronal dataset (ABA). 2.7 +Modern experimental techniques allow the expression levels of many genes at many locations to be compared.

This will will be useful for experimentation and also drug discovery because marker genes can be used to design interventions which selectively target individual cortical areas. This algorithm will support the development of new neuroanatomical methods; we will find a small panel of genes that can find many of the areal boundaries at once. The algorithm developed in Goal 2 will contribute to the creation of a better cortical map. 2.30 +The algorithm developed in Goal 1 will be applied to each cortical area to find a set of marker genes that uniquely picks out the target area.
