Schematic overview mapping of the analyzed brain nuclei with high c-fos-DAB density in coronal sections from rostral to caudal.

High c-fos density as indicator for neuronal activity in nuclei in the cortex (dark blue), striatum (light blue), hypothalamus (red), thalamus (dark brown), amygdala (green), and midbrain (yellow). Analyzed areas include cingulate cortex (Cg1/2), septohippocampal nucleus (Shi), nucleus accumbens core and shell (NAcc, NAcSH), ventral and dorsal parts of the hypothalamic lateral septal nucleus (LSV, LSD) as well as the dorsomedial nucleus (DM). In the thalamus, the medial habenular (MHb) nucleus and the lateral part of the central nucleus in the amygdala (CeL). Other regions included the bed nucleus of stria terminalis (BSTMA, BSTMV, light brown), and the periaqueductal gray (PAG). See also Table 1 for c-fos density (positive neurons per mm²) in each analyzed nucleus.
