In my Vertebrate Physiology class we are studying Parkinsons disease,
Huntingtons disease, etc. I know that Parkinson's disease deals with the
degeneration of dopamine cells in the brain, but what I don't know is how
and why these cells begin to break down. I have done a lot of research and
I still can not find the answer to this question. If anyone could help me I
would appreciate it.
