Abstract

Significance: Dopamine (DA) and serotonin (5-HT) release in the nucleus accumbens (NAc) influence motivated behaviors, yet the mechanisms by which they modulate NAc activity are unclear. Here, we report that DA selectively reduced excitatory postsynaptic currents (EPSCs) from paraventricular thalamus (PVT) inputs, whereas 5-HT reduced EPSCs from PVT, ventral hippocampus (vHip), and basolateral amygdala (BLA) inputs but not medial prefrontal cortex (mPFC) inputs. Mimicking the input-specific effect of DA via optogenetic inhibition of the PVT promoted cocaine-conditioned place preference, while inhibition of the mPFC blocked the enhancement of sociability induced by (±)3,4-methylenedioxymethamphetamine (MDMA). Together, these results suggest that these input-specific effects on NAc excitatory transmission contribute to the distinct modulation of behavior that is generated by release of DA and 5-HT.

  • Inhibition of basolateral amygdala-to-nucleus accumbens inputs enhanced sociability, but inhibition of ventral hippocampus-to-nucleus accumbens inputs decreased sociability.

    “Consistent with these findings, we found that inhibition of BLA-to-NAc inputs enhanced sociability but surprisingly observed a decrease in sociability when vHip-to-NAc inputs were optogenetically inhibited [65].”

  • Bath application of dopamine or methamphetamine depressed responses generated by paraventricular thalamus inputs while having minimal effects on those generated by ventral hippocampus, basolateral amygdala, and medial prefrontal cortex inputs.

    “In marked contrast, bath application of DA or methamphetamine (to release endogenous DA) depressed responses generated by PVT inputs while having minimal effects on those generated by the three other brain regions.”

  • Bath application of serotonin or MDMA depressed excitatory postsynaptic responses in D1 medium spiny neurons generated by ventral hippocampus, basolateral amygdala, and paraventricular thalamus inputs but spared those generated by medial prefrontal cortex inputs.

    “Bath application of 5-HT or MDMA (to release endogenous 5-HT) depressed excitatory postsynaptic responses in D1 medium spiny neurons generated by vHip, BLA and PVT inputs but surprisingly spared those generated by mPFC inputs.”

  • Inhibition of either paraventricular thalamus-to-nucleus accumbens or medial prefrontal cortex-to-nucleus accumbens inputs did not alter sociability, although the latter manipulation prevented the enhanced sociability elicited by systemic MDMA administration.

    “In contrast, inhibition of either PVTto-NAc or mPFC-to-NAc inputs did not alter sociability although the latter manipulation prevented the enhanced sociability elicited by systemic MDMA administration [65].”

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.
