7. 5. Conditional and non-conditional reward-related responses to alcohol. Nicotinic mechanisms

   Author : Elin Löf; Göteborgs universitet; []

   Abstract : The mesolimbic dopamine system is believed to mediate the positive reinforcing and rewarding effects of addictive drugs by increasing dopamine levels in its terminal area, the nucleus accumbens (nAc). Nicotinic acetylcholine receptors (nAChRs) within this system appear important for the pharmacological actions of both alcohol and nicotine, which may explain the frequent co-abuse of these two drugs.
