the present results underline the view that the high-affinity [ 3h ] nic and [ 3h ] ach binding sites label the same cholinergic nicotinic receptor binding site , while [ 125i ] btx labels another subpopulation of nicotinic cholinergic receptors , predominantly found in discrete areas of the hypothalamus and the limbic cortex .
