oxytocin

Oxytocin is a hormone produced in the paraventricular nucleus and supraoptic nucleus of the hypothalamus and released into the blood via the posterior lobe of the pituitary gland. It initiates contractions during childbirth and supports the milk ejection reflex during breastfeeding. It is also released during orgasm. Oxytocin can promote trust and strengthen pair bonding, but recent findings show that its effects are more complex and, in certain contexts, can also promote separation from out-groups.

Neurohypophysis

The neurohypophysis is the posterior lobe of the pituitary gland. It stores the hormones oxytocin and vasopressin, which are produced in the hypothalamus, and releases them into the bloodstream when needed.

1. Glossary

Paraventricular nucleus

A nucleus of the hypothalamus whose neurons produce various hormones, including oxytocin and vasopressin, which are transported to the neurohypophysis. The PVN sends axons to the limbic system, the brain stem, and other hypothalamic nuclei.

1. Glossary

Supraoptic nucleus

A core area of the hypothalamus, located above the optic nerves. This is where the peptide hormones vasopressin and oxytocin are produced.
