8.Parkinson's is characterized by the death of a population of neurons that produce dopamine — a neurotransmitter that regulates movement, among other things.
11.So the reason that vibration decreases painis because the physiology of the nervesof light touch, pressure, stretching and motionall races pain to the spine.
12.The role of Renshaw cells and inhibitory neurotransmitters is to fine-tune the action of the alpha motor neuron, which is in charge of sending the actual signal for contraction to the muscle.
13.Additionally, if there's damage to the nerves controlling eye movement, then eye movements can be painful and there can even be double vision, if the eyes can no longer move in a coordinated way.
14.Now, the neurons responsible for coordinating movement are located in a part of the brain called the striatum, which receives information from two major sources — the neocortex and a region known as the substantia nigra.
15.It's characterized by the deterioration and loss of both upper and lower motor Neurons as the motor Neurons stop sending signals the Muscles weaken leading to Paralysis When the muscles in the diaphragm are paralyzed this can be fatal.
