Impact of Neurotransmitters on Physical and Mental Behavior The neurons inside of the central and peripheral nervous system are responsible for all human activity. A Neurotransmitter is a chemical that is released by a neuron's terminal button. Neurotransmitters have either an excitatory or an inhibitory effect on the other nearby neurons. Neurotransmitters are a very important part of the Central Nervous System (CNS) because they allow communication to occur inside neurons as well as between neurons. The four primary neurotransmitters are acetylcholine, dopamine, GABA, and serotonin.
Acetylcholine is the primary neurotransmitter secreted by efferent axons of the CNS (Carlson, 2011, p. 99). Acetylcholine is made of two

This means that an Acetylcholine deficiency would seriously impair a human's ability to even think, let alone complete tasks. We naturally lose seven to ten milliseconds of processing speed every decade starting at age 40, but a deficiency (like that found in patients with Alzheimer's disease) would cause the degeneration to speed up. A deficiency in Acetylcholine can also cause anxiety, mood swings, bipolar disorder, impaired creativity, attention problems, and impaired abstract thinking (Jordon, 2008, ¶ 26). Low levels of acetylcholine can also cause physical issues such as excessive urination, inflammatory diseases, dry mouth and cough, osteoporosis, lack of motor control, reading and writing disorders, and multiple sclerosis (Jordon, 2008, ¶ 26).
Dopamine also can have an excitatory or inhibitory affect on neurons, depending on the postsynaptic receptor (Carlson, 2011, p. 102). Dopamine is created in the frontal lobes of the brain and is associated with our beta brain waves (Jordon, 2008, ¶14). Dopamine controls the electric voltage of the brain. Acting like a natural amphetamine, dopamine controls energy, excitement, and motivation (Jordon, 2008, ¶14). Dopamine plays an important role in many physical and psychological functions such as blood pressure, metabolism, digestion, voluntary movement,
