Abstract

Dorsal striatum is important for the development of drug addiction; however, a precise understanding of the roles of striatopallidal (indirect) and striatonigral (direct) pathway neurons in regulating behaviors remains elusive. Using viral-mediated expression of an engineered G protein-coupled receptor (hM(4)D), we found that activation of hM(4)D receptors with clozapine-N-oxide (CNO) potently reduced striatal neuron excitability. When hM(4)D receptors were selectively expressed in either direct or indirect pathway neurons, CNO did not change acute locomotor responses to amphetamine, but did alter behavioral plasticity associated with repeated drug treatment. Specifically, transiently disrupting striatopallidal neuronal activity facilitated behavioral sensitization, whereas decreasing excitability of striatonigral neurons impaired its persistence. These findings suggest that acute drug effects can be parsed from the behavioral adaptations associated with repeated drug exposure and highlight the utility of this approach for deconstructing neuronal pathway contributions to behavior.

  • Inhibition of striatal D2R or activation of D1R-expressing striatal neurons enhances sensitivity to the rewarding effects of drugs.

    “inhibition of striatal D2R or activation of D1R-expressing striatal neurons (which mediate signalling in the striatal direct pathway) enhance the sensitivity to the rewarding effects of drugs (71–73).”

    From Obesity and addiction: Neurobiological overlaps (2013) · cites this paper as [71]

  • In the striatum, D2Rs mediate indirect pathway signalling to frontal cortical regions; their down-regulation enhances sensitization to drugs, whereas up-regulation interferes with drug consumption.

    “In the striatum, D2Rs mediate signalling in the striatal indirect pathway that modulates frontal cortical regions; and their down-regulation enhances sensitization to the effects of drugs in animal models (68), whereas their up-regulation interferes with drug consumption (69,70).”

    From Obesity and addiction: Neurobiological overlaps (2013) · cites this paper as [68]

  • Inhibition of striatal D2R or activation of D1 receptor-expressing striatal neurons enhances sensitivity to drug rewards.

    “Moreover, inhibition of striatal D2R or activation of D1 receptor-expressing striatal neurons (mediate signaling in the striatal direct pathway) enhances the sensitivity to drug rewards (74).”

    From The Addictive Dimensionality of Obesity (2013) · cites this paper as [74]

  • In striatum, D2 receptors mediate indirect pathway signaling to frontocortical regions; down-regulation enhances drug sensitization, while upregulation interferes with drug consumption.

    “In the striatum, D2 receptors mediate signaling through the indirect pathway that modulates frontocortical regions, and its down-regulation enhances drug sensitization in animal models (74), whereas its upregulation interferes with drug consumption (75).”

    From The Addictive Dimensionality of Obesity (2013) · cites this paper as [74]

  • In the striatum, D2Rs mediate signaling from the striatal indirect pathway that modulates prefrontal regions, and downregulation of D2Rs in animal models has been shown to enhance sensitization to the effects of drugs.

    “In the striatum D2Rs mediate signaling from the striatal indirect pathway that modulates prefrontal regions, and its downregulation in animal models has been shown to enhance sensitization to the effects of drugs (Ferguson et al 2011).”

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.
