      The signals/messages from the brain to the body cross over these small gaps using substances called neurotransmitters. The nerve fibers that go from the brain to the muscles that are under our conscious control are the ones that are affected in Parkinson’s disease. These nerve fibers use a neurotransmitter called dopamine.
