 arvid carlsson (born 25 january 1923) is a swedish scientist who is best known for his work with the neurotransmitter dopamine and its effects in parkinson's disease. for his work on dopamine, carlsson was awarded the nobel prize in physiology or medicine in 2000, along with co-recipients eric kandel and paul greengard. carlsson was born in uppsala, sweden, son of gottfrid carlsson, historian and later professor of history at the lund university, where he began his medical education in 1941. in 1944 he was participating in the task of examining prisoners of nazi concentration camps, who folke bernadotte, a member of the royal swedish family, had managed to bring to sweden. although sweden was neutral during world war ii, carlsson's education was interrupted by several years of service in the swedish armed forces. in 1951, he received his m.l. degree (the equivalent of the american m.d.) and his m.d. (the equivalent of the american ph.d.). he then became a professor at the university of lund. in 1959 he became a professor at the university of gothenburg. in 1957 carlsson demonstrated that dopamine was a neurotransmitter in the brain and not just a precursor for norepinephrine, as had been previously believed.{{cite journal| author=arvid carlsson, margit lindqvist, tor magnusson| title=3,4-dihydroxyphenylalanine and 5-hydroxytryptophan as reserpine antagonists| journal=nature| volume=180| issue=4596| pages=1200|date=november 1957| pmid=13483
