Hypothalamus

Produces neurohormones that stimulate the pituitary gland to secrete hormones into the circulatory system. These hormones, in turn, stimulate endocrine glands to secrete hormones that stimulate target organs.

Receives input from:
 * Pyriform cortex: olfactory information.
 * Vomeronasal organ: pheromone olfactory information.
 * Taste buds: gustatory information.
