What are Neurotransmitters?


Neurotransmitters are chemicals that are released during a nerve impulse to either excite or inhibit nerve function. There are many neurotransmitters in the body, all of which work together to regulate motor coordination, behavior, temperature, pain mechanisms, blood flow and many other biochemical and physiological properties. When there is a disruption within the neurotransmitter system, it can cause abnormalities with all of these essential functions.

Dopamine is a commonly known neurotransmitter and is associated with Parkinson's Disease. Other examples of neurotransmitters are norepinephrine, epinephrine, serotonin and gamma-aminobytric (GABA).
