Nicotinic Receptors May be Important Targets for Treatment of Multiple Addictions
August 15, 2007
Researchers discovered that the rats most likely to self-administer addictive drugs had a particular receptor in the brain that is more responsive than the same receptor in rats least likely to self-administer addictive drugs. This receptor, known as the nicotinic acetylcholine receptor, increases excitability within the brain's reward centers.
