Figure 2
Schematic representation of the brain regions analyzed for c-Fos immunoreactivity. The distance from the bregma in the rostrocaudal plane is shown in parentheses in the medial preoptic area (mPOA, A), ventral tegmental area (VTA, B), nucleus accumbens (NAcc, C), ventral pallidum (VP, D), auditory cortex (Au, E) and olfactory bulb (OB, F) regions. Boxes represent the area histologically analyzed. The box in the mPOA covers subregions of the medial preoptic nuclei medial (100%) and lateral (50%), medial preoptic area (30%), medial preoptic area (30-40%) and anteroventral periventricular nucleus (100%). The drawings are coronal sections of the brain modified from Keith et al. [23]. LV, lateral ventricle; 3rd ventricle, third ventricle; AsbSh, Shell of NAcc; AcbC, Core of NAcc.
