Evidence for functional activity of up-regulated nicotine binding sites in rat striatal synaptosomes.


A number of studies have found that the chronic administration of nicotine causes an increase in the density of nicotinic binding sites in the brain, but it is not known whether these additional binding sites are functionally active receptors. In this study, the effects of 1-week administration of the potent nicotinic agonist, (+)-anatoxin-a (96 nmol/day… (More)
