Phasic Dopamine Release in Appetitive Behaviors and Drug Addiction

Abstract

Although dopamine is implicated in the development of addiction, it is unclear how specific dopamine release patterns are involved with drug seeking. Addictive drugs increase tonic dopamine levels on the order of minutes, as well as phasic dopamine release events that occur on a subsecond time scale. Phasic dopamine release is associated with the initiation of goal-directed behaviors, and has been shown to promote drug seeking. Prior experience with addictive drugs modulates the synaptic and intrinsic properties of dopamine neurons, affects the pattern of dopamine neuron firing and release, and alters dopamine-dependent behaviors related to drug addiction. In this review, we synthesize the known drug-dependent changes to the dopamine system along with the established functions of phasic dopamine release in order to provide a framework for conceptualizing the role of phasic dopamine release in drug addiction. Because drug addiction is commonly thought to involve changes in brain circuits important for natural reinforcement, we first present the role of phasic dopamine release in appetitive and goal-directed behaviors in the context of contemporary theories regarding the function of dopamine. Next, we discuss the known drug-induced changes to dopamine neurons and phasic release in both in vitro and in vivo preparations. Finally, we offer a simple model that chronic drug experience increases the contrast, or 'signal to noise', of phasic dopamine release to basal dopamine levels in response to drug-related stimuli, which could result in aberrant associations between cues and reinforcers that contribute to the development 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.
