Oxytocin affects social distance between adult males and females, and may be responsible at least in part for romantic attraction and subsequent monogamous pair bonding. An oxytocin nasal spray caused men in a monogamous relationship, but not single men, to increase the distance between themselves and an attractive woman during a first ...
The oxytocin receptor, also known as OXTR, is a protein which functions as receptor for the hormone and neurotransmitter oxytocin. [4] [5] In humans, the oxytocin receptor is encoded by the OXTR gene [6] [7] which has been localized to human chromosome 3p25. [8] Evolutionary tree of the oxytocin, vasotocin, mesotocin and isotocin receptors and ...
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.
Oxytocin is another chemical in the feel good cocktail that orgasm produces and one that affects women more so than men—namely because “when female brains develop in utero there are more ...
Neurochemistry is the study of the different types, structures, and functions of neurons and their chemical components. Chemical signaling between neurons is mediated by neurotransmitters, neuropeptides, hormones, neuromodulators, and many other types of signaling molecules.
The oxytocin and vasopressin that is released at the posterior pituitary gland enters the blood, and cannot re-enter the brain because the blood–brain barrier does not allow oxytocin and vasopressin through, but the oxytocin and vasopressin that is released from dendrites acts within the brain. Oxytocin neurons themselves express oxytocin ...
Neurophysins are carrier proteins which transport the hormones oxytocin and vasopressin to the posterior pituitary from the paraventricular and supraoptic nucleus of the hypothalamus, respectively. Inside the neurosecretory granules, the analogous neurophysin I and II form stabilizing complexes via covalent interactions. [ 1 ]
The nervous and endocrine systems often act together in a process called neuroendocrine integration, to regulate the physiological processes of the human body. Neuroendocrinology arose from the recognition that the brain, especially the hypothalamus , controls secretion of pituitary gland hormones, and has subsequently expanded to investigate ...
