I am doing an beginning student into college and am currently doing an initial research assgmt of the Parkinson s disease. This is because I had a neighbor die last fall. I realize it s too complicated for me to learn all at this point, but would like to see some sort of picture displaying the travel of the neurons (or however you say it) to which they affect the brain. I understand the conditions relating afterward, but can you provide some large general picture of this transaction? Hope this is an understandable request. Thank you.
