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.
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.
Findings provide additional insight into how the circadian clock regulates physiological function.
Researchers have discovered a group of neurons in the retina that affect circadian rhythm by sending signals to the SCN.
According to new research, chimpanzees have almost the same personality trails as humans.
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.
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.
Findings provide a new insight into how the brain regulates food and water intake.
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.
According to a new study, the hormone arginine vasopressin promotes trust and cooperation in humans who are in risky situations.
