FIGURE 6

Guanine nucleotide binding protein (G protein), gamma 2 (Gng2), is expressed throughout the insular cortex but relatively weakly in layers 5/6. At striatal levels (B,D), dense expression is observed in the ventral claustrum (vCLA) and dorsal endopiriform nucleus (DEn). Expression in the dorsal claustrum (dCLA) but it is relatively weaker (D). The same distribution of expression is evident anterior to the striatum (A,C) albeit with weaker expression throughout the claustrum-endopiriform complex. Note in A and C, the separation of DEn from vCLA with the emergence of the lateral orbital cortex (LO). (E,F) are schematic representations of Gng2 expression (green) rostral to the striatum and at striatal levels, respectively. acc, nucleus accumbens; CPu, caudate/putamen; ec, external capsule; fm, forceps minor of the corpus callosum; Ins, insular cortex; Pir, piriform cortex. Scale bars in A,B = 800 μm; C,D = 500 μm.
