“…DA is released in the medial preoptic area (MPOA) and nucleus accumbens following copulation and exposure to chemosensory stimuli in male rodents (Asmus, 1994; Balfour et al, 2004; Damsma et al, 1992; Mas et al, 1990; Meisel et al, 1993; Mitchell and Gratton, 1992; Pfaus et al, 1990; Sato et al, 1995; Schulz et al, 2003; Wenkstern et al, 1993). In fact, the MPOA DA release in hamsters requires exposure to female chemosensory stimuli (Triemstra et al, 2005), further reinforcing the obligatory nature of chemosensory stimuli for sexual responses in this species. DA is implicated in CPP for sexual behavior in hamsters, as CPP induced by sexual behavior in female hamsters is blocked by administration of a D2 receptor antagonist (Meisel et al, 1996, but see Agmo and Berenfeld, 1990; Agustin-Pavon et al, 2007 for different findings in other rodent species).…”
