Phosphorylated ERK 1/2 (44/42 kDa) in the NAc and CPu. (A) NAc pERK protein levels are reduced after pre-treatment with MK-801 and (B) positively correlated to CPP scores. (C & D) CPu pERK protein levels and correlation to CPP scores. Phosphorylated protein levels are expressed as a ratio to their respective total protein levels and expressed as percentage of saline controls (n = 6 per group). *Significant difference at p <0 .05. (E) Illustration indicating location of tissue from which brain punches used for protein analysis were taken.
