	pERK		pCREB		FosB		ΔFosB
	Male	Female	Male	Female	Male	Female	Male	Female
NAc	0.22	−0.09	0.34	0.26	−0.43	−0.69	0.42	−0.05
CPu	0.82	0.09	−0.76	−0.10	0.20	−0.12	0.09	−0.09
PfC	0.32	0.35	−0.23	0.52	−0.38	−0.07	−0.35	−0.38
HIP	−0.02	−0.30	−0.06	0.54	−0.52	0.03	−0.34	−0.58

Correlations were assessed between total locomotor counts during the CPP test and protein levels normalized to saline controls of the respective sex (n = 4 animals per group). Bold values indicate a significant correlation at p < 0.05.
