Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. [4] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.
The biology of romantic love has been explored by such biological sciences as evolutionary psychology, evolutionary biology, anthropology and neuroscience.Specific chemical substances such as oxytocin and dopamine are studied in the context of their roles in producing human experiences, emotions and behaviors that are associated with romantic love.
An increase in vasopressin has been observed in female rats which have just given birth. Vasopressin is associated with aggressive and hostile behaviours, and is postulated to decrease sexual motivation in females. Vasopressin administered in the female rat brain has been observed to result in an immediate decrease in sexual motivation. [13]
Two important neuropeptides that mediated pair bond formation were oxytocin and arginine vasopressin (AVP). Even though both males and females have both molecules, oxytocin was shown to be predominantly in females and vasopressin predominantly promoted pair bonding in males. [1]
Falling in love is the development of strong feelings of attachment and love, usually towards another person. The term is metaphorical, emphasizing that the process, like the physical act of falling, is sudden, uncontrollable and leaves the lover in a vulnerable state, similar to "fall ill" or "fall into a trap".
Most recently she has been examining the role of oxytocin and vasopressin in mental disorders such as autism, schizophrenia, anxiety and depression. [6] Carter is also known for research on the physiological basis of social behavior , including studies that implicated oxytocin, vasopressin and hormones of the hypothalamic-pituitary-adrenal ...
In humans, there is evidence that oxytocin and vasopressin are released during labor and breastfeeding, and that these events are associated with maternal bonding. According to one model, social isolation leads to stress, which is associated with activity in the hypothalamic-pituitary-adrenal axis and the release of cortisol .
Most of the circulating oxytocin and vasopressin hormones are synthesized in magnocellular neurosecretory cells of the supraoptic nucleus and paraventricular nucleus of the hypothalamus. They are then transported in neurosecretory granules along axons within the hypothalamo-neurohypophysial tract by axoplasmic flow to axon terminals forming the ...
