RT-PCR Gene expression in the hippocampus (n = 8/condition). a Dopamine receptor D1 gene―DrD1, b Dopamine receptor D2 gene―DrD2, c Opioid receptor µ―Oprm1. d Cannabinoid receptor 1―CNR1. The columns represent means and the vertical lines ± S.E.M of relative (2-ΔΔCt method) gene expression in the striatum of OF1 mice. * p < 0.05 significant differences with respect to the CTRL group
