ISH patterns of cortical area-selective genes in adult macaque cortex. Parasagittal sections (5 mm away from the central sulcus) of ISH for AA-selective genes, RBP4, SLIT1, and PMNA5 (A) and primary visual area (V1)-selective genes, HTR1B, HTR2A, and FSTL1 (B). Scale bar: 10 mm. A, B, Right two sides show enlargements of regions boxed in the left photo. The arrowheads indicate the expression of the AA-selective genes of RBP4 and PNMA5 in upper layer 2 in V1. Scale bar, 0.5 mm.
