(a) Zif268 expression was analyzed by immunocytochemistry in the dorsal striatum (DStr, upper panel) and the nucleus accumbens (NAcc, lower panel) one hour after acute administration of cocaine (20 mg/kg) or its vehicle. SL327 (50 mg/kg) was administered one hour prior to cocaine (SL327 + cocaine). Scale bar 100 �m (b) Quantification of Zif268 immunoreactive cells was performed in the dorsal striatum (DStr, left panel) or the nucleus accumbens (NAcc, right panel) using an image analyzer (Image Pro Plus). Data (means � SEM, n = 3 per group) were analyzed using one-way ANOVA: effect of treatment in the DStr F(2, 8) = 50.99, P < 0.001, and the NAcc F(2, 8) = 82.24, P < 0.001. Post hoc comparison (Newman-Keuls test), * p < 0.01, saline vs cocaine and � p < 0.01 cocaine vs SL327 + cocaine.
