The effect of HFS on kindling relapse during postextinction stages. Morph + sham: control group; morph + DBS: experimental group; pre = preconditioning CPP score; post = postconditioning CPP score; extinction = extinction CPP score; relapse = relapse CPP score. indicates . The results suggest that high-frequency DBS stimulation during withdrawal period will inhibit the rats’ relapse behavior.
