Effects of unilateral intra-accumbens infusion of baclofen (220 pmol) or of muscimol (220 pmol) on c-fos activity in selected brain regions.

Counts of labelled neurons in each of the brain regions, given for (left columns) the vehicle infused side and the baclofen infused side and (right columns) the vehicle infused side and the muscimol infused side. Significant differences from vehicle are shown:*p**pThe areas investigated were VP (ventral pallidum at β–0.26 mm); LH1 (lateral hypothalamus at β–1.6 mm); LH2 (lateral hypothalamus at β–2.6 mm); LH3 (lateral hypothalamus at β–3.6 mm); LH4 (lateral hypothalamus at β–4.3 mm); Arc (arcuate nucleus at β–2.8 mm); PVN (paraventricular nucleus of the hypothalamus at β–1.88 mm); CeA (central nucleus of the amygdala at β–3.14 mm); BLA (basolateral nucleus of the amygdala at β–3.3 mm); VTA (ventral tegmental area at β–5.3 mm).
