Illustration of the D4R (in green) single immunofluorescence studies in the claustrum (a) and in the dorsal endopiriform nucleus (b) of the rat brain. Microphotographs from coronal sections of rat brain at Bregma ( + 1.00 mm) level. A medium density of D4R IR nerve cell bodies and proximal dendrites with moderate to high IR (in green) is observed within the claustrum (a) and in the DEn (b). D4R IR is also observed in CPU but with a more diffuse appearance. Images are representative for the three rats studied. Scale bars are shown.
