Abstract

Paternal care plays a critical role in the development of brain and behaviors in offspring in monogamous species. However, the neurobiological mechanisms, especially the neuronal circuity, underlying paternal care is largely unknown. Using socially monogamous male mandarin voles (Microtus mandarinus) with high levels of paternal care, we found that paraventricular nucleus of the hypothalamus (PVN) to ventral tegmental area (VTA) or nucleus accumbens (NAc) oxytocin (OT) neurons are activated during paternal care. Chemogenetic activation/inhibition of the PVN OT projection to VTA promoted/decreased paternal care, respectively. Chemogenetic inhibition of the PVN to VTA OT pathway reduced dopamine (DA) release in the NAc of male mandarin voles during licking and grooming of pups as revealed by in vivo fiber photometry. Optogenetic activation/inhibition of the VTA to NAc DA pathway possibly enhanced/suppressed paternal behaviors, respectively. Furthermore, chemogenetic activation/inhibition of PVN to NAc OT circuit enhanced/inhibited paternal care. This finding is a first step toward delineating the neuronal circuity underlying paternal care and may have implications for treating abnormalities in paternal care associated with paternal postpartum depression or paternal abuse. SIGNIFICANCE STATEMENT Paternal behavior is essential for offspring survival and development in some mammalian species. However, the circuit mechanisms underlying the paternal brain are poorly understood. We show that manipulation of paraventricular nucleus of the hypothalamus (PVN) to ventral tegmental area (VTA) oxytocin (OT) projections as well as VTA to nucleus accumbens (NAc) DA projections promote paternal behaviors. Inhibition the PVN to VTA OT pathway reduces DA release in the NAc during pup licking and grooming. PVN to NAc OT circuit is also essential for paternal behaviors. Our findings identify two new neural circuits that modulate paternal behaviors.

  • The emergence of paternal behavior is driven in part by oxytocin activity in the mesolimbic dopamine system.

    “The emergence of paternal behavior, similar to maternal behavior, is driven in part by OT activity in the mesolimbic DA system [36,37].”

    From The Neurobiology of Love and Pair Bonding from Human and Animal Perspectives (2023) · cites this paper as [37]

    The Abstract reports that manipulating oxytocin projections to the ventral tegmental area changed paternal care in male mandarin voles, and inhibiting those projections reduced dopamine release in the nucleus accumbens during pup care. The Paternal behavior test section shows that the study examined fathers caring for their own pups, not the emergence or onset of paternal behavior. The source therefore supports a role for this circuit in active paternal care, but not the claim about its emergence. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • In mandarin voles, paternal behavior is facilitated by the activation of oxytocin projection neurons from the paraventricular nucleus of the hypothalamus to the ventral tegmental area and nucleus accumbens.

    “In mandarin voles (Microtus mandarinus), paternal behavior is faciliated by the activation of OT projection neurons from the paraventricular nucleus of the hypothalamus (PVN) to the VTA and NAc [37].”
  • Paraventricular oxytocin projections to the ventral tegmental area and nucleus accumbens promote paternal behaviors in mandarin voles.

    “Other loci of PVN OXT action include the VTA and NAcc as PVN OXT projections to these areas promote paternal behaviors in mandarin voles ( 126).”

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.
