Abstract

BDNF, Dopamine, and Cocaine Reward: The nucleus accumbens plays a crucial role in mediating the rewarding effects of drugs of abuse. Different subpopulations of nucleus accumbens projection neurons exhibit balanced but antagonistic influences on their downstream outputs and behaviors. However, their roles in regulating reward behaviors remains unclear. Lobo et al. (p. 385 ) evaluated the roles of the two subtypes of nucleus accumbens projection neurons, those expressing dopamine D1 versus D2 receptors, in cocaine reward. Deleting TrkB, the receptor for brain-derived neurotrophic factor, selectively in each cell type, and selectively controlling the firing of each cell type using optogenetic techniques allowed for confirmation that D1- and D2-containing neurons produced opposite effects on cocaine reward.

  • TrkB is enriched in D2 medium spiny neurons.

    “TrkB is enriched in D2-MSNs and BDNF signaling through TrkB has different roles in NAc MSN subtypes in psychostimulant and opiate motivation (26, 70), but depression-related BDNF signaling in MSN subtypes is unclear.”
  • BDNF signaling through TrkB has different roles in nucleus accumbens medium spiny neuron subtypes in psychostimulant and opiate motivation.

  • 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 [73]

  • Optogenetic stimulation of D1-type medium spiny neurons in rodents enhances reward driven behaviors, whereas stimulations of D2-type medium spiny neurons results in freezing behavior.

    “For example, optogenetic stimulation of D1-type medium spiny neurons in rodents enhances reward driven behaviors, whereas stimulations of D2-type medium spiny neurons results in freezing behavior (Lobo et al., 2010).”

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.
