Effects of neonatal manipulations on D1 and D2 dopamine receptor protein levels in basal ganglia nuclei of adult male rats. A. Representative immunoblots corresponding to D1, D2 receptors and β-actin (used as internal control) from total homogenates of caudate-putamen (CPu) and nucleus accumbens (NAc). B. Bar graphs depicting D1 and D2 protein levels in CPu and NAc (expressed as percent of control). Data are presented as mean ± SEM; n = 4–8 rats/group; * statistically significant manipulation effect (P < 0.05, one-way ANOVA followed by post-hoc analysis); C: control; BMS: brief maternally separated; PMS: prolonged maternally separated rats.
