Figure 2

Locations and subdivisions of visual, auditory, entorhinal, and retrosplenial cortices. Panels (A–G) and (I–K) are ISH-stained sections while panels (H,L) are Nissl-stained sections. (A–D) Four rostral (A) to caudal (D) coronal sections showing Rorb expression in L4 of the primary and secondary visual and auditory cortices (V1, V2M, V2L, A1, and A2) as well as in the caudal S1. Note the strong and moderate Rorb expression in the primary (V1, S1, and A1) and secondary/association (A2, V2M, V2L) sensory cortices, respectively. No or little Rorb expression is seen in the RS. (E–G) Three rostral (E) to caudal (G) sections showing little and strong Plch1 expression in L3 of the lateral and medial entorhinal cortex (LEC and MEC), respectively. (H) A Nissl-stained section showing the locations of the Pro, PaS, and L2 of the MEC. (I–L) Four sections stained respectively for Tshz2 (I), Penk (J), Cux2 (K), and Nissl (L) showing the locations of three RS subdivisions (RSg, RSag, and RSagl), which display differential molecular signature and cytoarchitecture. (M–P) Four sections stained respectively for Rbp4(M), Etv1 (N), Adcyap1 (O), and Foxp2 (P) showing lamination of the RS. Note the thick L5 in the RS, which can be subdivided into 5a and 5b. Bar: 350 μm in panel (A) (for all panels).
