Gene expression in BLAa and BLAp. (A) In situ hybridization images from the Allen Brain Atlas, a genome wide gene expression atlas, ⁸ showing that magnocellular BLAa neurons express Rspo2, while parvocellular BLAp neurons express primarily Ppp1r1b. Additional genes highlight the genetic similarity within the BLAa and their distinction from BLAp. (B and D) Genes Fhl2, 3110035D14Rik, Fxyd6, and Etv1, among others not shown here, are expressed primarily in BLAa and not BLAp. (C and E) Genes Dcn, Nnat, Wfs1, and Col6a1, among others not shown here, are expressed primarily in BLAp and not BLAa.
