" Dr. Robert Burke, the Alfred and Minnie Bressler Professor of Neurology (in Pathology) at Columbia University Medical Center, and his colleague Ms. Tinmarla Francis Oo, senior staff associate at Columbia University Medical Center, further discovered that the dopamine deficit came from disintegration, not of the dopamine neurons themselves, but of their axons, the long, filament-like structures responsible for transmitting dopamine to distant targets in the brain. Their insights, says Dr. Li, are helping us understand the disease at a deeper level -- something that will lead us to better treatments and possibly even a cure for Parkinson's disease.
