The brain model that is used to explain movement is in serious need of updating. To view the brain as being housed only in the head confines us to an illogical acceptance of the presentation of Parkinson's disease as well as other neurological diseases. In order for the Parkinson's model to work and make any sense, it would mean that the brain MUST be present throughout the entire body. If that is not the case, then Parkinson's disease is NOT a brain disease at all. That is not to say that the "brain" is not affected, but it is to say that the "brain" is but one area that is affected by a much more widespread intruder.

What is affected? Our ability to move, smell, speak, hear correctly, breathe correctly, peristalsis and proper bowel function, etc. are among the affecterd areas. The only neurological entity that I can find that is proximal to and influences the functioning of all these areas of the body is the Vagus Nerve. When this nerve becomes inflamed acetylcholine production is overstimulated which creates a problem in afferent and efferent nerve impulses that allow proper extension and contraction in muscle tissue. Attempting to explain all of these varied symptoms by using our current brain model just does not work.
