Furthermore, disinhibition of areas of the brain which inhibit the release or noradrenaline also nullify the effect of stress-induced reinstatement.

These hypophysiotropic hormones go on to stimulate or inhibit the release of hormones from the anterior pituitary.

This inhibits the release of parathyroid hormone, which can result in hypoparathyroidism and hypocalcemia.

Dopamine inhibits the release of prolactin, so dopamine levels must drop in order for prolactin levels to rise.

This results in hyperpolarization of cholinergic neurons, which inhibits the release of acetylcholine.
