The Dopamine Effect in Parkinson's Disease

People have assumed that maybe if you were to look at how much dopamine is being released to the trisome, you would just get the faster you move, the more dopamine you have. And this is actually one of the questions that these authors addressed. They did the correlation and they found no good evidence that that is true. If anything, there might be a slight negative correlation. So that at least in small timescale, like on the order of seconds, if a mouse is moving fast, that tends to be maybe less dopamine. When the mouse is stopping, there may be more dopamine, which is counterintuitive.
