(A–D) SV2C is expressed in the caudate nucleus (Cd), the putamen (Pu), globus pallidus (GP), nucleus accumbens (NAc), thalamus (Thal), and cortex of rhesus macaques. SV2C expression is also observed in the neuropil of the midbrain (E), with possible expression in the cell bodies (black arrows) of the substantia nigra pars compacta (SNc) and the ventral tegmental area (VTA) (F–G).
