Emx2 cortical area map phenotypes. Outline drawings of cortical map phenotypes in wild type mice and mice over expressing Emx2 show changes in the shape of PMBSF and V1. 1A shows PMBSF for wild-type and ne-Emx2 homozygote. 1B shows V1 drawings from wild-type, ne-Emx2 heterozygote, and ne-Emx2 homozygote. Rostral is up, lateral is right. In both areas, increasing Emx2 expression produces rostral elongation, although in PMBSF the lateral edge appears more affected than the medial edge.
