The Effect of High-Frequency Electrical Stimulation of Bilateral Nucleus Accumbens on the Behavior of Morphine-Induced Conditioned Place Preference Rats at Extinction and Reinstatement Phases

Figure 3

The effect of HFS on the extinction phase of morphine CPP in rats: the experimental group did not regress successfully during the 9 electrical stimulations; control group got successful induction of extinction after third stimulation, which showed the inhibition of extinction in the experimental group.
