Opioid limbic circuit for reward: interaction between hedonic hotspots of nucleus accumbens and ventral pallidum

Abstract

Mu-opioid stimulation of cubic millimeter hedonic hotspots in either the nucleus accumbens shell (NAc) or the ventral pallidum (VP) amplifies hedonic "liking" reactions to sweetness and appetitive "wanting" for food reward. How do these two NAc-VP hotspots interact? To probe their interaction and limbic circuit properties, we assessed whether opioid activation of one hotspot recruited the other hotspot (neurobiologically) and whether opioid hedonic and incentive motivational amplification by either opioid hotspot required permissive opioid coactivation in the other (behaviorally). We found that NAc and VP hotspots reciprocally modulated Fos expression in each other and that the two hotspots were needed together to enhance sucrose "liking" reactions, essentially cooperating within a single hedonic NAc-VP circuit. In contrast, the NAc hotspot dominated for opioid stimulation of eating and food intake ("wanting"), independent of VP activation. This pattern reveals differences between limbic opioid circuits that control reward "liking" and "wanting" functions.

  • Pleasurable or rewarding experiences comprise an anticipatory 'wanting' component and an 'in-the-moment enjoyment' (liking) component.

    “Current evidence suggests that, cognitively, pleasurable or rewarding experiences, in general, comprise a “looking forward to” anticipatory component, which is cognitively driven (i.e., “wanting”) (23, 24), and an “in-the-moment enjoyment” (i.e., “liking”) component (25, 26).”

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.
