(born Jan. 25, 1923, Uppsala, Swed.) Swedish pharmacologist. He received his M.D. from the University of Lund. Carlsson established that dopamine is an important neurotransmitter, showing that high levels of dopamine are found in areas of the brain that control walking and other voluntary movements. He determined that levodopa, a substance that the brain uses to make dopamine, could be employed as a treatment for parkinsonism. His work also contributed to an understanding of the relationship between neurotransmitters and mental states such as clinical depression, which led to new antidepressant drugs, including Prozac. Along with Eric Kandel and Paul Greengard, Carlsson was awarded the Nobel Prize in 2000.

Carlsson, Arvid, 1923-, Swedish pharmacologist, grad. Univ. of Lund, Sweden, (M.D., Ph.D., 1951). Carlsson was a professor at the Univ. of Lund (1951-59) and at the Univ. of Gothenburg, Sweden (1959-89). In 2000 he, Paul Greengard, and Eric Kandel were awarded the Nobel Prize in physiology or medicine for their discoveries concerning signal transduction in the nervous system. The nerve cells in the human brain are linked by a complex network of nerve processes, with messages being transmitted via various chemical transmitters. Carlsson was cited for discovering that dopamine is one of those transmitters and that it is critical to movement control. His research led to the realization that lack of dopamine in certain parts of the brain causes Parkinson's disease. See also neurotransmitter.

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,[1] 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.[2][3]

While working at Astra AB, Carlsson and his colleagues were able to derive the first marketed selective serotonin reuptake inhibitor, zimelidine, from brompheniramine.[1]

Carlsson developed a method for measuring the amount of dopamine in brain tissues. He found that dopamine levels in the basal ganglia, a brain area important for movement, were particularly high. He then showed that giving animals the drug reserpine caused a decrease in dopamine levels and a loss of movement control. These effects were similar to the symptoms of Parkinson's disease. By administering to these animals L-Dopa, which is the precursor of dopamine, he could alleviate the symptoms. These findings led other doctors to try using L-Dopa on patients with Parkinson's disease, and found it to alleviate some of the symptoms in the early stages of the disease. L-Dopa is still the basis for most commonly used means of treating Parkinson's disease.[1]

Opposition to fluoridation of drinking water

Carlsson is opposed to the fluoridation of drinking water.[4][5] He took part in the debate in Sweden, where he helped to convince Parliament that water fluoridation should be illegal due to ethics. He believes that water fluoridation violates modern pharmalogical principles, which indicate that medications should be tailored to individuals.[6]
