Hi Brian! Bo Johnels, the neurology-professor at my hospital, believes that involuntary movements (paraphrased by me, I've forgotten the wording) is the result of dopamine receptors detecting a decrease of dopamine levels, cranking up their sensitivity to dopamine, and then producing way too powerful signals to the muscles when dopamine comes into the system. How about that as an explanation? It sounds believable to me... /John. On Mon, 2 Aug 1999, Brian Collins wrote: > > I ask every Neurologist the same question: What is Dyskinesia?
