What part of the brian does the disease affect and where does dopamine originate? (anonymous)
Parkinson's disease "affects" different areas of the brain but primarily the dopamine-producing section called the substantia nigra. The symptoms of the disease, however, are mostly due to the lack of dopamine in the striatum, a group of brain structures involved in the control of movement. The reason why the symptoms are due to striatum dysfunction is that the substantia nigra normally sends its dopamine to the striatum, where it is used to regulate automatic movements.
