Abstract

Based on brain imaging findings, we present a model according to which addiction emerges as an imbalance in the information processing and integration among various brain circuits and functions. The dysfunctions reflect (a) decreased sensitivity of reward circuits, (b) enhanced sensitivity of memory circuits to conditioned expectations to drugs and drug cues, stress reactivity, and (c) negative mood, and a weakened control circuit. Although initial experimentation with a drug of abuse is largely a voluntary behavior, continued drug use can eventually impair neuronal circuits in the brain that are involved in free will, turning drug use into an automatic compulsive behavior. The ability of addictive drugs to co‐opt neurotransmitter signals between neurons (including dopamine, glutamate, and GABA) modifies the function of different neuronal circuits, which begin to falter at different stages of an addiction trajectory. Upon exposure to the drug, drug cues or stress this results in unrestrained hyperactivation of the motivation/drive circuit that results in the compulsive drug intake that characterizes addiction.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Addiction involves impairments in circuits involved with self-control, decision-making, interoception, and mood and stress regulation.

    “there are impairments in circuits involved with self-control and decision-making, interoception and mood and stress regulation (8).”

    From Obesity and addiction: Neurobiological overlaps (2013) · cites this paper as [8]

  • The urge to seek and consume drugs in addiction involves disruption of reward circuitry and other circuits including interoception, inhibitory control, mood/stress regulation, and memory.

    “The overwhelming urge to seek and consume the drug in addiction involves disruption not only of the reward circuitry but also of other circuits, including interoception, inhibitory control, mood and stress regulation, and memory (39).”

    From The Addictive Dimensionality of Obesity (2013) · cites this paper as [39]

  • Allostatic theory asserts reward insensitivity and negative reinforcement underlie the later and more severe stages of addiction.

    “but reward insensitivity and negative reinforcement underlie the later and more severe stages(18–20).”

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.
