abstract：:It is well established that chronic nicotine treatment produces a dose-dependent increase in high-affinity L-[3H]nicotine binding. This increase may be due to chronic desensitization of the receptor. Sophisticated kinetic analyses of high-affinity nicotine binding to rat brain have demonstrated that the association ra...
