abstract：:Recent observations from synaptosome preparations have questioned the tetrodotoxin (TTX) insensitivity of nicotine-evoked release in the striatum, a characteristic previously considered diagnostic of presynaptically located nicotinic acetylcholine receptors (nAChRs). Therefore, we have undertaken a comparison of nicot...
