What hormones are produced and released in the brain?

A hormone, wherever it is formed, that is delivered to the target tissue via the blood is called an endocrine (endo = within + crine = to secrete) hormone. They may be or protein or steroid structure.

Neurons that make hormones are located in the hypothalamus. The hormones produced are oxytocin and antidiuretic hormone which are stored in the posterior pituitary (neurohypothalamus). They are still distributed as the other endocrine hormones are.
