What kind of scientist did both Paul Greengard and Eric Kandel serve as?
Paul Greengard Paul Greengard (born December 11, 1925) is an American neuroscientist best known for his work on the molecular and cellular function of neurons. In 2000, Greengard, Arvid Carlsson and Eric Kandel were awarded the Nobel Prize for Physiology or Medicine for their discoveries concerning signal transduction in the nervous system. He is currently Vincent Astor Professor at Rockefeller University, and serves on the Scientific Advisory Board of the Cure Alzheimer's Fund, as well as the Scientific Council of the Brain & Behavior Research Foundation. He is married to artist Ursula von Rydingsvard.
Edward Kravitz Edward Arthur Kravitz (born December 19, 1932) is the George Packer Berry Professor of Neurobiology at Harvard Medical School. He is widely recognized for demonstrating that gamma-aminobutyric acid (GABA) functions as a neurotransmitter. In addition, he and Antony Stretton were the first to use the intracellular dye procion yellow to visualize neuronal architecture. Later, Kravitz’s work with neuroamines demonstrated that serotonin and octopamine act as synaptic modulators. Kravitz continued to explore the function of amines using "Homarus americanus", the American lobster, as a model organism to study aggression. He currently works on aggressive behavior using the genetically manipulable model organism, "Drosophila melanogaster", the fruit fly.
