Figure 2. Immunohistofluorescent analysis of brains derived from tdTomDAT-Cre and tdTomDAT-CreERT2 mice identifies tdTOM-positive cell bodies in the LS, LHb, and the amygdala. Series of coronal sections from the level of the striatum and NAc through to the raphe nucleus showing expression pattern of recombination in (A–G) tdTomDAT-Cre and (H–N) tdTomDAT-CreERT2 mice (scale bar: 2 mm). Expression of tdTOM-positive neurons in the (O, T) lateral septum, (P, U) LHb, (Q, V) BLP, (R, W) arcuate nucleus, and (S, X) the premammilary nucleus of the hypothalamus in tdTomDAT-Cre and tdTomDAT-CreERT2 mice (scale bar: 100 μm). ADP, anterodorsal preoptic nucleus; Arc, arcuate nucleus; CPu, caudate putamen; DR, dorsal raphe; Hyp, hypothalamus; LS, lateral septum; MFB, medial forebrain bundle; MHb, medial habenula; PAG, periaquaductal gray; Pe, periventricular hypothalamic nucleus; STN, subthalamic nucleus; ZI, zona incerta; BLP, Basolateral amygdaloid nucleus posterior division; BNST, Bed nucleus of the stria terminalis; CeA, Central amygdala, CLi, Caudal linear nucleus; NAc, Nucleus accumbens; MePD, Medial amygdaloid nucleus posterodorsal part, and LHb, Lateral habenula, PMH, Premammillary nucleus; RMN, Retromammillary nucleus; RRF, Retrorubral field; SNc, Substantia nigra pars compacta; SNr, Substantia nigra pars reticulata; VTA: Ventral tegmental area.
