Oxytocin, a hormone commonly associated with love and bonding in humans, causes starfish to turn their stomachs inside-out to feed. The findings provide vital new evidence for the evolutionary role of oxytocin and vasopressin neuropeptides as regulators of feeding in animals.
Male patients on the autism spectrum who were given oxytocin for four weeks experienced improvements in social attachment behaviors for up to 12 months.
A new measuring method has detected oxytocin at much higher rates in blood serum and plasma than researchers previously thought.
Mouse mothers gathering their pups train female mice without pups to perform the same behavior. In virgin mice, observing the mother mouse take care of her pups stimulates oxytocin production, biologically shaping them for maternal behavior.
Expectant fathers with higher levels of brain activation and oxytocin later endorsed a more "child-led" empathetic style of parenting once their child was born.
Researchers discovered people with a specific variant of the oxytocin receptor gene OXTR follow more people on Instagram. However, there no evidence was found to suggest gene-environment interactions influence online sociability.
A single dose of oxytocin can enhance brain activity while processing social information in children with autism, a new study reports.
Soybean oil, the most consumed cooking oil in the US, has been linked to neurological and metabolic alterations in mice. Soybean oil-fed mice showed decreased levels of oxytocin in the hypothalamus.
Early-life exposure to antibiotics may impact brain signaling pathways associated with social behavior and pain regulation. Young mice treated with antibiotics had reduced expression of receptors that mediate endorphin, oxytocin, and vasopressin signaling in the frontal cortex.
People who experienced sexual abuse or suffer from PTSD have reduced connectivity in the ventral and dorsal attention network (VAN-DAN network) compared to those with no history of abuse or PTSD.
