What kind of scientist did both Paul Greengard and Eric Kandel serve as?
neuroscientist
Title: Paul Greengard
Passage: 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.
Title: The Brain That Changes Itself
Passage: The Brain That Changes Itself: Stories of Personal Triumph from the Frontiers of Brain Science is a book on neuroplasticity by psychiatrist and psychoanalyst Norman Doidge, M.D.  It features numerous case studies of patients suffering from neurological disorders and details how in each case the brain adapts to compensate for the disabilities of the individual patients, often in unusual and unexpected ways.  Interviews with the patients, clinicians, and research scientists involved in these studies make up a large portion of the contents.  Doidge uses examples of previous work carried out by neuroscientists such as Paul Broca, Sigmund Freud, Alexander Luria, Donald O. Hebb, Paul Bach-y-Rita, and Eric Kandel to show that the brain is adaptive, and thus plastic.  Through the case studies, Doidge demonstrates both the beneficial and detrimental effects that neuroplasticity can have on a patient, saying, "... neuroplasticity contributes to both the constrained and unconstrained aspects of our nature."  However, according to Doige, neuroplasticity "... renders our brains not only more resourceful, but also more vulnerable to outside influences."
Title: Eric Kandel
Passage: Eric Richard Kandel (] ; born November 7, 1929) is an Austrian-American neuroscientist and a University Professor of biochemistry and biophysics at the College of Physicians and Surgeons at Columbia University.  He was a recipient of the 2000 Nobel Prize in Physiology or Medicine for his research on the physiological basis of memory storage in neurons.  He shared the prize with Arvid Carlsson and Paul Greengard.
