Arvid check here Carlsson and Paul Greengard shared in 2000 the most recent Nobel Prize for Physiology or Medication that arrived from catecholamine exploration.

Carlsson identified that in the brain DA functions as a neurotransmitter in its own right. DA plays a critical position in regulation of movement. Loss of DA within the nigrostriatal program generates the movement condition that defines Parkinson disease (PD), and replenishment of DA by administration of its precursor l-DOPA fast increases motion in sufferers with PD.
