Remembering Paul Greengard

Paul Greengard was awarded one-third of the 2000 Nobel Prize in Physiology or Medicine for his work on signal transduction in the nervous system. His key discovery was of a second messenger, a chemical compound in the receiving neuron in the brain that would initiate activity downstream of the initial interneuron message. He was also the founder of the Pearl Meister Greengard Prize, named after his mother, awarded to distinguished women in the field of biology.
