Neuroendocrine regulation and behavior

The paper investigates how maternal brain activity responds to social moments during caregiving, identifying four processes linked to oxytocin and social behavior.

This study shows that Magel2 deficiency causes reduced neurite outgrowth and glutamatergic synapses, which are partially rescued by postnatal oxytocin treatment in mice.

This study shows that oxytocin acts on astrocytes in the central amygdala to promote a positive emotional state, challenging the notion that oxytocin only affects neurons.

The paper examines how social rank affects neural activation in mice in response to familiar or unfamiliar social cues from dominant or subordinate males.

This study investigates sex differences in the vasopressin system of the ventral pallidum and their association with juvenile social play behavior in rats.

The paper identifies a brain-wide circuit that modulates micturition behavior based on social and sensory contexts in mice.

This study shows that estrogen withdrawal increases anxiety-like behaviors by altering oxytocin signaling in the paraventricular hypothalamus and dorsal raphe nucleus in Syrian hamsters.

This study reconstructs the hypothalamo-neurohypophysial system's structure and function, revealing MNCs' role in both peripheral and central oxytocin actions.

The paper identifies that parvocellular oxytocin neurons are critical for autism-related social reward behavior and show enrichment of autism risk genes in these neurons.

This study examines how early-life temperature exposure impacts thyroid hormone receptor signaling and DNA methylation in female rat pups, linking these changes to epigenetic regulation in the paraventricular nucleus.

The paper shows that vasopressin signaling in the PVN buffers stress-induced synaptic changes in female mice but not males.

The paper shows that specific extra-hypothalamic oxytocin neurons regulate stress-induced social anxiety behaviors by modulating social vigilance and approach.

This study investigates the acute effects of prolactin on Prlr-expressing neurons in the hypothalamus of mice, revealing diverse electrical responses across different brain regions.

The paper evaluates how social and food preferences vary in Wistar rats and C57BL/6J mice under different conditions, finding differences in baseline preferences and responses to deprivation.

This study shows that mice can learn to use a specific sound cue to improve their maternal behavior in retrieving pups, demonstrating sensory learning's role in modifying stereotyped maternal actions.

This study investigates how oxytocin modulates amygdala responses during top-down and bottom-up aversive anticipation in individuals with varying trait anxiety levels.

The paper examines gene expression correlates of social variation in coral reef butterflyfishes, finding sexually dimorphic differences in social-related gene expression within species but consistent patterns across species transitions.

This study shows oxytocin excites BNST interneurons and inhibits BNST output neurons to the central amygdala, suggesting a role in facilitating cued fear.

The paper shows that maternal approach behaviors toward neonatal mouse calls are influenced by the mother's prior experience with pups carrying a risk gene variant for autism.

This study measures binding affinities of oxytocin, vasopressin, and Manning compound at oxytocin and V1a receptors in Syrian hamster brains, revealing species-specific receptor promiscuity.

The paper investigates neural activity differences in poison frog tadpoles that win, lose, or avoid fights, finding distinct patterns in brain regions associated with aggression.

The paper identifies a neuronal ensemble in the nucleus accumbens that expands with pair bonding in prairie voles, suggesting it underlies bond formation and maturation.

The paper quantifies OTR cell distribution in postnatal mouse brains using fluorescent reporter mice and 3D template brains, revealing spatial and temporal patterns and sexually dimorphic nuclei.

This study examines how genetic and early environmental factors influence maternal care in mice, showing differential susceptibility to rearing conditions based on DRD4 genotype.

The paper examines hormonal and neural correlates of parental care in poison frogs, finding that neural activity patterns, not hormones or gene expression, correlate with active parental behavior in both sexes.

The paper examines how TIDA neurons in mice adapt their activity during lactation and weaning, finding reversible changes in oscillation frequency and Ih current.

This study examines the sex-specific effects of oxytocin on social behavior and hypothalamic oxytocin cells in adult rats, finding no effect on hippocampal neurogenesis.

This study examines how oxytocin affects salivary testosterone and oestradiol levels in autistic and typical women, finding distinct hormonal responses between groups.

This study compares intranasal and intravenous oxytocin administration effects on regional cerebral blood flow, showing systemic OT increases drive amygdala perfusion changes and validating intranasal targeting of specific brain regions.
