Dr. Allerton recognized that in order for the brain to function properly and for the neurotransmitters in the brain to receive messages, the hypothalamus must be working correctly, since it is the functioning center for four of the brains most powerful hormones (neurotransmitters) that affect the mind; Serotonin, Dopamine, Norepinephrine and acetylcholine.  It was his feeling that improper Hypothalamic function could be the cause of most of the mental problems/chemical imbalances that affect children and adults.

The general functions of the hypothalamus are of extreme importance to the body, such as:

The main function of the hypothalamus is homeostasis, or maintaining the body's status quo. Factors such as blood pressure, body temperature, fluid and electrolyte balance, and body weight are held to a precise value called the set-point. Although this set-point can migrate over time, from day to day it is remarkably fixed.
