it also says levodopa can cause symptoms of pd - which, while i am not sure that that is inaccurate (have done some interesting reading on levodopa-induced apoptosis recently) i am not sure what feedback inhibition is.

people should really provide sources on wikipedia.

i have never heard of DAs (or levodopa, i don't think) causing increased receptor sensitivity, nor have i ever heard of such a thing being responsible for pd symptoms - like rick said, it would seem to fly in the face of logic.
