The hidden island of addiction: the insula

Open access
Naqvi, Nasir H., Bechara, Antoine·2009·Trends in Neurosciences

Abstract

Most prior research on the neurobiology of addiction has focused on the role of subcortical systems, such as the amygdala, the ventral striatum and mesolimbic dopamine system, in promoting the motivation to seek drugs. Recent evidence indicates that a largely overlooked structure, the insula, plays a crucial part in conscious urges to take drugs. The insula has been highlighted as a region that integrates interoceptive (i.e. bodily) states into conscious feelings and into decision-making processes that involve uncertain risk and reward. Here, we propose a model in which the processing of the interoceptive effects of drug use by the insula contributes to conscious drug urges and to decision-making processes that precipitate relapse.

  • Imaging studies report differential activation of the insula during craving, possibly reflecting interoceptive cues and hypothesised to involve CRF activation.

    “Consistent with this hypothesis, imaging studies have reported differential activation of the insula during craving, possibly reflecting interoceptive cues and hypothesised to involve CRF activation (table 2, circuit 18).54,117,118”

    From Neurobiology of addiction: a neurocircuitry analysis (2016) · cites this paper as [54]

    The Evidence for the role of the insula in addiction section reports imaging activation of the insula during drug urges, and the Proposed role section links those urges to interoceptive representations. The Anatomy and function section notes CRF receptors in the insula and a possible role in stress-related motivation to take drugs, but it does not link the reported imaging activation during craving to CRF activation. (LLM, conf=0.86)

  • The insula has long been implicated in drug cravings, the maintenance of drug-seeking behavior, and the regulation of distress during withdrawal.

    “The insula has long been implicated in drug cravings, the maintenance of drug-seeking behavior, and the regulation of distress during withdrawal [1,6,71].”

    From The Insular Cortex: An Interface Between Sensation, Emotion and Cognition (2024) · cites this paper as [6]

    The 'Evidence for the role of the insula in addiction' section links insula activity to drug urges and relapse or continued use. The 'Proposed role for the insula in addiction' section suggests that the insula might translate withdrawal-related bodily signals into dysphoria, but does not establish that it regulates distress during withdrawal. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Dysfunction of interoception is increasingly recognized as an important component of anxiety disorders, mood disorders, eating disorders, addictive disorders, and somatic symptom disorders.

    “Dysfunction of interoception is increasingly recognized as an important component of different mental health conditions, including anxiety disorders, mood disorders, eating disorders, addictive disorders, and somatic symptom disorders.”

    From Interoception and Mental Health: A Roadmap. (2018) · cites this paper as [102]

    The sections on interoception and addiction link interoceptive processes and insula dysfunction to drug addiction. The paper does not establish dysfunctional interoception as an important component of anxiety, mood, eating, or somatic symptom disorders; its discussion of fear, sadness, and hunger concerns experiences, not those diagnoses. Page numbers are not available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Drug addiction is marked by interoceptive disturbances, with overlapping neural circuitry and abnormal responses to interoceptive cues.

    “Drug addiction, another condition marked by interoceptive disturbances, has an overlapping neural circuitry and abnormal responses to interoceptive cues (101–104).”

    From Interoception and Mental Health: A Roadmap. (2018) · cites this paper as [102]

    In “Proposed role for the insula in addiction” (page unavailable), the paper describes a hypothesized shift in how drug-related bodily sensations are valued and links interoceptive effects to the insula and related regions. This supports altered responses to interoceptive signals in addiction, but the paper presents much of the mechanism as a model rather than an established finding and does not establish neural-circuit overlap with another condition. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The insula appears to have an interoceptive function integrating autonomic and visceral information with emotion and motivation, providing conscious awareness of urges.

    “The insula appears to have an interoceptive function that integrates autonomic and visceral information with emotion and motivation, thus providing conscious awareness of these urges.54”

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.
