Born 25 Jan 1923.

He is a Swedish neuroscientist who shared (with Paul Greengard and Eric R. Kandel) the 2000 #NobelPrize in #Medicine or Physiology “for their discoveries concerning signal transduction in the #NervousSystem.” He made fundamental contributions to understanding of the #brain through his research on #SynapticTransmission—the method of communication between #neurons.

He discovered the roles of #seratonin and #dopamine as chemical #neurotransmitters, thus adding a whole new mode of action to the existing knowledge of electrical neurotransmission (via action potentials). His work led to the development of #levodopa, te first drug to treat #Parkinson's disease symptons. #Carlsson also introduced the first selective re-uptake inhimitor, #zimelidine, which led to development of #Prozac and Zoloft for the treatment of #depression.
