Drinking water can suppress the vasopressin hormone receptor, mitigating obesity and metabolic syndrome in mice.
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.
Lower levels of vasopressin were present in the cerebrospinal fluid of infants who later went on to be diagnosed with autism.
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.
Hydration signals from the gut travel via the vagus nerve to activate thirst neurons in the SFO. These neurons signal to cells in the median preoptic nucleus, driving animals to drink and the kidneys to conserve water in the bloodstream.
A new study of male rhesus macaques reveals exposure to oxytocin and vasopressin 'flattens' group hierarchy, forcing dominant males to become more relaxed and subordinate monkeys to become more confident.
A new study that used rhesus macaques with low levels of sociability revealed the animals had reduced levels of vasopressin in their cerebral spinal fluid, as did children diagnosed with ASD.
A new study reveals a connection between light sensitive nerve cells in the eyes and areas of the brain that regulate mood. The findings may help explain how light can induce some of the negative emotions that often accompany migraines.
Researchers have discovered a group of neurons in the retina that affect circadian rhythm by sending signals to the SCN.
Findings provide a new insight into how the brain regulates food and water intake.
