Study suggests loss of 2 types of neurons -- not just 1 -- triggers Parkinson's symptoms
...ins. "We know that norepinephrine is important for regulating the activity of dopamine neurons, so we suspected that the dopamine neurons and the norepinephrine neurons function in concert. As the dopamine neurons start dying, the norepinephrine neurons compensate by signaling the surviving dopamine cells to dr...Old McDonald's has a hold on kids' taste buds, Stanford/Packard study finds
