Dopamine, oxytocin, and vasopressin receptor binding in the medial prefrontal cortex of monogamous and promiscuous voles

Abstract

Comparisons between monogamous and promiscuous vole species have proven useful in examining neurobiological mechanisms underlying social attachment. Reward processing is important for social attachment, and the medial prefrontal cortex (mPFC) exerts a direct influence on reward pathways. Dopamine (DA), oxytocin (OT), and arginine vasopressin (AVP) all have been implicated in the regulation of social attachment in monogamous voles. Therefore, we used radiolabeled ligands to examine dopamine D(1)- and D(2)-like, OT, and AVP V(1a) receptor binding densities in the mPFC of monogamous and promiscuous voles. Species differences were found; monogamous voles had higher densities of D(2)-like and OT receptor binding and lower densities of D(1)-like and V(1a) receptor binding than did promiscuous voles. Sex differences also were found; females had higher densities of OT receptor binding but lower densities of V(1a) receptor binding than did males in both species. Further, the laminar distribution of receptor binding indicates the possibility of an interaction between DA and OT systems in the mPFC in the regulation of social attachment. Differences in D(1)- and D(2)-like receptor binding between species are discussed in terms of how they might modulate cortical activity and subsequent DA release in the nucleus accumbens (NAcc).

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.
