Abstract

Opioids are the most potent analgesics in clinical use; however, their powerful rewarding properties can lead to addiction. The scientific challenge is to retain analgesic potency while limiting the development of tolerance, dependence, and addiction. Both rewarding and analgesic actions of opioids depend upon actions at the mu opioid (MOP) receptor. Systemic opioid reward requires MOP receptor function in the midbrain ventral tegmental area (VTA) which contains dopaminergic neurons. VTA dopaminergic neurons are implicated in various aspects of reward including reward prediction error, working memory, and incentive salience. It is now clear that subsets of VTA neurons have different pharmacological properties and participate in separate circuits. The degree to which MOP receptor agonists act on different VTA circuits depends upon the behavioral state of the animal, which can be altered by manipulations such as food deprivation or prior exposure to MOP receptor agonists.

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

  • Other neuromodulators, such as opioids, are more intrinsic to reward than dopamine.

    “Other neuromodulators, such as opioids, seem to be more intrinsic to reward in that regard (e.g. Fields and Margolis, 2015).”

    From The theory of constructed emotion: an active inference account of interoception and categorization (2016) · cites this paper as Fields and Margolis, 2015

    The section “Both dopaminergic and non-dopaminergic circuits can contribute to VTA opioid reward” says opioid reward can occur without normal dopamine function. That supports a narrower point about opioid reward, but the paper does not establish that opioids are generally more intrinsic to reward than dopamine; it also describes dopamine’s role as dependent on the animal’s state.

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.
