Explanation

For the development of treatment for Parkinson’s disease, the Swedish neuroscientist Arvid Carlsson was awarded the Nobel Prize in Physiology or Medicine in the year 2000. He discovered that dopamine is an important neurotransmitter in the brain, and in Parkinson’s disease the nerve cells that produce dopamine in the basal ganglia gradually degenerate, which leads to tremor, rigidity, and akinesia. His research showed that Parkinson’s disease occurs due to a deficiency of dopamine in certain parts of the brain, and an effective medicine (L-dopa) can be developed for it.
