Open in a separate window. The Mesolimbic Reward System When drugs stimulate mu opioid receptors in the brain, cells in the ventral tegmental area VTA produce dopamine and release it into the nucleus accumbens NAc , giving rise to feelings of pleasure. The Neurobiological Basis of Dependence and Withdrawal The locus ceruleus LC is an area of the brain that is critically involved in the production of opioid dependence and withdrawal.

Definitions of Key Terms. Cognitive Deficits Model The cognitive deficits model of drug addiction proposes that individuals who develop addictive disorders have abnormalities in an area of the brain called the prefrontal cortex PFC.

Methadone Methadone is a long-acting opioid medication. Naltrexone Naltrexone is used to help patients avoid relapse after they have been detoxified from opioid dependence.
