The Role of the Striatopallidal and Extended Amygdala Systems in Drug Addiction

KOOB, GEORGE F.·1999·Annals of the New York Academy of Sciences

Abstract

ABSTRACT: Evidence Suggests that the acute reinforcing actions of drugs of abuse may be mediated by specific elements of the striatopallidal and extended amygdala systems. These include the shell of the Nucleus accumbens, the central nucleus of hte amygdala, and the sublenticular extended amygdala. Chronic administration of drugs of abuse, including cocaine, amphetamines, nicotine, alcohol, and tetrahydrocannabinol leads to an increasing dysregulation of brain reward systems that is characterized by decreases in reward function. Withdrawal from chronic administration of cocaine, amphetamine, nicotine, alcohol, and tetrahydrocannabinol raises thresholds for brain stimulation reward. Neurochemical elements in the extended amygdala may mediate these changes, including decreases in dopamine and serotonin neurotransmission in the nucleus accumbens and increases in the brain‐stress neurotransmitter, corticotropin‐releasing factor, in the central nucleus of the amygdala. The combination of decreases in function of neurotransmitters involved in the positive‐reinforcing properties of drugs of abuse with recruitment of brain‐stress systems within the extended amygdala provides a powerful mechanism for allostatic changes in hedonic set point that can lead to the compulsive drug‐seeking and drug‐taking behavior characteristic of addiction.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
