(A) Relative levels of dopamine receptor (DR)-D2 messenger ribonucleic acid (mRNA) in the rostral to caudal subregions of the nucleus accumbens (Acb) of animals allowed access to a running wheel for 6 weeks (Exercised; n=10) or housed under sedentary, locked wheel, conditions (Sedentary; n=9). Values represent mean integrated density ± standard error of measurement. * p<.05 with respect to Sedentary. Representative autoradiographs showing in situ hybridization for DR-D2 mRNA in the Acb of sedentary (B) and exercised (C) rats. CPu, caudate putamen.
