Neurotransmission   Neurotransmission is the speed of reactions within the nervous system and brain. It involves the conversion of electrical energy to chemical energy back to electrical energy as impulses move from nerve to nerve. Neurotransmission is affected by the abundance or deficiency of certain neurotransmitters, the quantity of oxygen the brain receives and the amount of energy the brain cells are able to utilize. Excessively fast neurotransmission can cause anxiety and nervous tension while slow neurotransmission is associated with mental fatigue, a lack of creativity and depression.

Neurotransmitters   Neurotransmitters are chemicals in the brain that create a wide spectrum of feelings, moods and thoughts. The five main neurotransmitters addressed by BCOP are norepinephrine, dopamine, serotonin, GABA, and acetylcholine.

Norepinephrine   Norepinephrine is an excitatory neurotransmitter associated with heightened alertness, muscle activity, blood flow within vessels, elevated heart rate, and the opening of bronchioles in the respiratory tract. Normal levels provide the ability to react quickly and aggressively to demanding situations and danger and help protect against depression associated with a lack of will to take on projects or challenges. Low levels can manifest as ADD, obesity, insomnia, disorientation, slowed thoughts or impotence. High levels can result in talking fast, a racing heart beat, faster breathing, weight loss, increased sex drive and excessive energy.
