Chronic nicotine treatment increases α4(nonα6)β2^* nAChR expression but does not affect α6β2^* nAChR density in nucleus accumbens shell

¹²⁵I-Epibatidine binding assays in the presence of α-CtxMII and ¹²⁵I-α-CtxMII were done to determine α4(nonα6)β2^* and α6β2^* nAChR expression, respectively, as described under Materials and Methods. Each value represents the mean ± S.E.M. of 10 animals per group.
