Nicotine binds preferentially to nicotinic Nicotine binds preferentially to nicotinic acetylcholinergicacetylcholinergic ((nAChnACh) receptors in the ) receptors in the central nervous system; the primary is the central nervous system; the primary is the αα44ββ2 nicotinic receptor in the Ventral 2 nicotinic receptor in the Ventral Tegmental Area (VTA)Tegmental Area (VTA)
After nicotine binds to the After nicotine binds to the αα44ββ2 nicotinic receptor in the VTA, it results in a release of 2 nicotinic receptor in the VTA, it results in a release of dopamine in the Nucleus Accumbens (dopamine in the Nucleus Accumbens (nAccnAcc) which is believed to be linked to reward) which is believed to be linked to reward
