Neural Mechanisms of Addiction
View through CrossRef
Addiction is a behavior characterized by compulsive seeking and taking of drugs despite severe negative consequences. Goal-directed behaviors and the motivation to perform these behaviors are altered in human addicts so that obtaining and using addictive drugs becomes the primary and overwhelming focus of their behavior. These altered behaviors result from maladaptive reward learning in which associations between drugs and drug-associated stimuli become powerful and enduring factors guiding behavior. Neural mechanisms specific to learning are likely to underlie addiction. This chapter provides an overview of both types of neural mechanisms and how they may interact to produce addiction.
