Neuroendocrine regulation and behavior

This study shows that oxytocin enhances trust acquisition in male mice but blocks trust violation learning, while its antagonist has similar effects, with no impact on females.

The paper examines how paternal experience in male mice affects aromatase expression in specific brain regions, linking it to changes in paternal behavior and brain lateralization.

This study shows that social defeat affects pair bond formation differently in male and female prairie voles, with BNST CRH neurons playing a sex-specific role in regulating these changes.

This study shows that blocking the CRF1 receptor in male mice prevents morphine-induced sociability deficits and oxytocinergic neuron firing, with sex-specific effects.

This study examines how male CD-1 mice respond molecularly to changes in social hierarchy, finding greater stress and gene expression changes in formerly dominant mice during social descent.

The paper investigates sex differences in aggression and neural substrates in Astatotilapia burtoni using behavioral assays and immunohistochemistry to analyze neural activation patterns.

This study investigates turn-taking aggressive behavior in Siamese fighting fish, identifying a brain region involved in persistence but not coordination of social interactions.

This study shows that visual identification of conspecifics influences social behavior in mice, highlighting the role of vision in social interactions.

This study uses microendoscopic imaging to show dynamic changes in oxytocin neuron activity in mother mice during lactation and weaning, revealing flexible adjustments in single-cell activity patterns.

This study develops a protocol to induce territorial behaviors and dominance hierarchies in laboratory mice, revealing differences in hierarchy formation between strains.

This study examines short-term social isolation effects on vocal and non-vocal social behaviors in prairie voles, finding no overall impact but sex- and context-specific changes in aggression.

The paper shows that social dysfunction in mice is linked to selective gene expression impairment in parvocellular oxytocin neurons, which can be mitigated by neonatal chemogenetic stimulation.

The paper identifies neural molecular mechanisms in wild cleaner fish during mutualistic interactions, finding genes related to learning, memory, and feeding behavior.

This study examines how aging affects pair bonding in prairie voles, finding sex-dependent behavioral changes and increased oxytocin-producing neurons with age.

This study shows that vasopressin in the lateral septum regulates social play behavior differently in male and female rats through glutamate, not GABA, with no sex differences in V1aR-expressing cell types.

The paper investigates FoxP2-positive neuron activity in tadpoles during begging and aggression, finding increased activation in specific brain regions associated with social behavior.

This study examines the effects of intranasal oxytocin in Oprm1 knockout mice, finding dose- and context-dependent improvements in social behavior and gene expression changes.

The paper introduces the Two-intruders test to study social communication in mice, finding that male preference for female intruders correlates with testosterone levels and involves odor recognition and hypothalamic activation.

This study examines sex differences in behavioral and neuroendocrine responses to aggression in California mice, finding that females show increased freezing behavior and males show increased vasopressin-c-fos co-localization after repeated aggression.

This study shows that male medaka use two distinct androgen receptor pathways to decide whether to mate or fight, with Ara promoting aggression and Arb promoting courtship.

This study shows oxytocin, but not vasopressin, reduces willingness to harm others by increasing guilt and shame for intentional harm.

This study maps oxytocin neuron projections in marmoset brains, revealing extensive connections to social behavior-related regions, similar to rodent patterns.

This study shows that Magel2 deficiency in mice leads to impaired discrimination of social fear and safety, linked to reduced oxytocin neuron activity in the supraoptic nucleus.

This study shows that androgen receptor signaling is required for male but not female aggression in Astatotilapia burtoni.

This study investigates how oxytocin (OT) neurons in the paraventricular nucleus (PVN) and their projections to the medial prefrontal cortex (mPFC) modulate pup care or infanticide in virgin mandarin voles.

This study investigates how serotonin and its receptor 5-HT1A modulate social competence in a fish species, finding that serotonin, but not 5-HT1A, influences submissive and threat behaviors during social interactions.

This study uses computer vision to analyze mother-infant interactions in V1b receptor knockout mice, finding that these mice retrieve pups more efficiently despite reduced movement.

The paper identifies brain circuits involved in prairie vole pair bonding using whole-brain mapping and finds that bonding-related circuits are largely sexually monomorphic and show coordinated activity between pair members.

The paper identifies a hypothalamic oxytocin circuit that mediates defeat-induced social avoidance learning in mice.

This study shows that dopamine release in the nucleus accumbens differs between interactions with pair bonded partners and novel voles, reflecting the selective nature of pair bonds.
