Description:
|
Imaging technology has played a pivotal role in advancing our understanding of the neurochemical and functional changes that characterize the addicted brain. Although the involvement of dopamine in drug reinforcement is well recognized, its role in drug addiction is much less clear. Imaging studies have shown that the reinforcing effects of drugs of abuse in humans are contingent upon large and fast increases in dopamine that mimic but exceed in the intensity and
duration those induced by dopamine cell firing to environmental events.

Abstract:
|
(CIT): Imaging technology has played a pivotal role in advancing our understanding of the neurochemical and functional changes that characterize the addicted brain. Although the involvement of dopamine in drug reinforcement is well recognized, its role in drug addiction is much less clear. Imaging studies have shown that the reinforcing effects of drugs of abuse in humans are contingent upon large and fast increases in dopamine that mimic but exceed in the intensity and duration those induced by dopamine cell firing to environmental events.
