(A) Representative photomicrograph showing immunohistochemical verification of Cre-dependent ChR2 (green) in tyrosine-hydroxylase positive cells (red) in VTA. (B) Quantified eYFP expression of ChR2 in VTA is displayed where light shading represents minimal spread and darker shading represents maximal spread of viral expression at each level. (C) Dense viral transfection was noted in terminals in nucleus accumbens. (ACBs) Nucleus accumbens shell, (ACBc) nucleus accumbens core, (aca) anterior commissure.
