Neuroendocrine regulation and behavior

This study shows that the orbitofrontal cortex promotes alloparental caregiving in female mice by modulating dopamine dynamics during behavior acquisition.

This study shows that same-sex mounting in single-housed C57BL/6J female mice is not influenced by the estrous state of either the mounter or the stimulus female.

This study shows that isogenic female mice form stable social hierarchies, with high-ranked females showing greater sociability and different dopamine and glucocorticoid receptor signaling compared to males.

This study shows that juvenile mice retain strong maternal preference post-weaning, which remains resilient to immune activation, with sex-specific differences in exploration behavior.

This study shows that sociability and social hierarchy are genetically separable in amniotes through PAS1 mutations in mice and wallabies/chickens.

This study shows that juvenile mice develop caregiving behavior through rapid neural circuit remodelling in the medial preoptic area, mediated by microglia.

The paper identifies sex-biased gene expression in the juvenile rat medial amygdala associated with playfulness, showing inhibitory neurons drive this difference.

The paper shows that oxytocin receptor-expressing BNST neurons are excited by AVP and OT inputs, reducing anxious arousal and threat avoidance.

The paper identifies a subset of VMHSF1 neurons in male mice that encode conspecific social cues with sex bias and drive social investigation, distinct from neurons involved in predator defense.

This study shows that oxytocin receptor absence in prairie voles impairs peer relationship formation, stability, and reward, with reduced oxytocin release in the nucleus accumbens.

This study examines social hierarchy formation in sex-changing fish, finding that dominance is size-based and disruption leads to rapid behavioral and neural changes.

This study investigates the effects of intranasal oxytocin on functional recovery after juvenile frontal traumatic brain injury, finding mixed behavioral improvements and increased brain oxytocin levels.

The paper builds a cellular atlas of the hypothalamic preoptic area in two deer mouse species, identifying cell types linked to behavioral differences and sex-specific evolution.

This study investigates how oxytocin and its antagonist affect risky decision-making in male and female rats, finding sex-dependent effects on reward preference.

The paper examines sex steroid receptor expression in Otp glutamatergic neurons of the medial extended amygdala and finds sex differences in receptor expression and neuronal morphology.

This study shows oxytocin regulates blood flow and permeability in the neurohypophyseal system to enhance its own uptake into the bloodstream.

The paper investigates how early social experience in fish affects neuroplasticity markers in brain regions related to social decision-making.

The paper uses single-nucleus RNA-sequencing to link molecular variation in hypothalamic neurons to social motivation behavior in mice, identifying actionable targets for social deficit disorders.

This study examines AVPR1a and OXTR receptor densities in schizophrenia patients and controls, finding age- and sex-dependent changes in the superior temporal sulcus and hypothalamus.

The paper identifies hypothalamic neurons that promote social behavior after short-term isolation, showing sex- and context-dependent effects.

Opposing glutamatergic MPN Isolation and mostly GABAergic MPN Reunion neurons in the mouse preoptic hypothalamus encode social need and satiety, with touch as a likely cue.

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.

This study identifies dopamine-dependent transcriptional changes in the dorsal hippocampal formation during pregnancy and postpartum, showing how dopamine modulates neural plasticity and behavior.

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 shows that vasopressin neurons in the hypothalamus regulate maternal thermoregulatory behaviors in mice, influenced by ambient temperature and TRPM8 thermosensation.

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.
