Oxytocin is a naturally occurring cyclic peptide produced by the hypothalamus and secreted by the pituitary gland. It functions as both a hormone and neurotransmitter within the brain. Research has shown that its synthetic form mimics the natural hormone and is studied for its potential to enhance trust, empathy, and social interactions. Oxytocin is particularly important during childbirth and lactation, where it induces uterine contractions and stimulates milk ejection. This peptide remains a key focus in research exploring its diverse physiological and psychological effects.
