Imaging the Addicted Human Brain
Modern imaging techniques enable researchers to observe drug actions and consequences as they occur and persist in the brains of abusing and addicted individuals. This article presents the five most commonly used techniques, explains how each produces images, and describes how researchers interpret them. The authors give examples of key findings illustrating how each technique has extended and ...
متن کاملThe addicted human brain: insights from imaging studies.
Imaging studies have revealed neurochemical and functional changes in the brains of drug-addicted subjects that provide new insights into the mechanisms underlying addiction. Neurochemical studies have shown that large and fast increases in dopamine are associated with the reinforcing effects of drugs of abuse, but also that after chronic drug abuse and during withdrawal, brain dopamine functio...
متن کاملThe addicted human brain viewed in the light of imaging studies: brain circuits and treatment strategies.
Imaging studies have provided evidence of how the human brain changes as an individual becomes addicted. Here, we integrate the findings from imaging studies to propose a model of drug addiction. The process of addiction is initiated in part by the fast and high increases in DA induced by drugs of abuse. We hypothesize that this supraphysiological effect of drugs trigger a series of adaptations...
متن کاملThe Addicted Brain
example is inflammation: perhaps the simplest form of pathology.

When these characteristics are present, the pathology/disease can be diagnosed. If it occurs in the lung it will indicate pneumonia, in the kidney nephritis etc. Likewise, a brain chronic...
