The Neurobiology of Cocaine Addiction
Cocaine produces its psychoactive and addictive effects primarily by acting on the brain's limbic system, a set of interconnected regions that regulate pleasure and motivation. An initial, short-term effect -- a buildup of the neurochemical dopamine -- gives rise to euphoria and a desire to take the drug again. Researchers are seeking to understand how cocaine's many longer term effects produce...

متن کاملGlutamate systems in cocaine addiction.
All addictive drugs facilitate dopamine transmission, and determining the role of dopamine has been the predominant focus of biomedical research in addiction for 20 years. Newer data and hypotheses have begun to shift our focus to involvement of cortex and corticofugal glutamate projections. The rationale for shifting focus to glutamate ranges from evidence showing that cortical activity is alt...
متن کاملCocaine addiction: psychology and neurophysiology.
Cocaine was considered incapable of producing dependence in 1980 but was recently proclaimed the drug of greatest national health concern. Recent clinical and preclinical investigations demonstrate that cocaine produces unique abuse and withdrawal patterns that differ from those of other major abused drugs and suggest that long-term cocaine abuse produces neurophysiological alterations in speci...
