Learning Mechanisms in Addictive Disorders
Learning Mechanisms in Addictive Disorders
Addictive disorders may best be described as attribution of salience to drug-associated cues and drug consumption at the expense of other reinforcers. Dopamine and serotonin dysfunction can contribute to these states due to drug-associated neuroadaptation and alterations in bottom-up and top-down information processing. Relevant findings are described with respect to their computational and behavioral implications.
