Definition
Eric Kandel is an American neuroscientist and professor of biochemistry and molecular pharmacology, best known for his research on the physiological basis of memory storage in neurons. He was awarded the Nobel Prize in Physiology or Medicine in 2000 for his discoveries concerning signal transduction in the nervous system.
Overview
Born on November 7, 1929, in Vienna, Austria, Kadeln emigrated with his family to the United States in 1939 to escape Nazi persecution. He earned his undergraduate degree at Harvard University (B.A., 1952) and his medical degree at Harvard Medical School (M.D., 1956). After completing a residency in internal medicine at Massachusetts General Hospital, he shifted his focus to neurobiology, completing post‑doctoral work at the National Institutes of Health (NIH) and later joining the faculty at the College of Physicians and Surgeons, Columbia University, where he has remained for most of his academic career. His seminal work with the sea‑slug Aplysia californica elucidated the cellular and molecular mechanisms of synaptic plasticity, demonstrating how long‑term potentiation and long‑term depression underlie learning and memory. Kandel has authored several influential texts, including the widely used textbook Principles of Neural Science.
Etymology/Origin
The name “Eric” derives from Old Norse Eirikr, meaning “ever ruler” or “eternal ruler.” The surname “Kandel” is of Germanic origin, potentially linked to the town of Kandel in Rhineland‑Palatinate, Germany, or to occupational roots referring to a candle maker (from German Kandel meaning “candle”). In Kandel’s case, the surname reflects his family’s Ashkenazi Jewish heritage.
Characteristics
- Research Focus: Molecular and cellular mechanisms of learning and memory, particularly synaptic changes in the nervous system.
- Methodology: Utilized simple model organisms (e.g., Aplysia) to dissect neural circuitry, combined electrophysiology, molecular biology, and behavioral assays.
- Key Discoveries: Identification of that long‑term memory formation requires new protein synthesis and structural changes at synapses; elucidation of the role of CREB (cAMP response element‑binding protein) in consolidating memories.
- Awards and Honors: Nobel Prize in Physiology or Medicine (2000); Albert Lasker Award for Basic Medical Research (1998); National Medal of Science (2010); elected to the National Academy of Sciences, American Academy of Arts and Sciences, and other prestigious societies.
- Professional Roles: Professor at Columbia University; former director of the Center for Neurobiology and Behavior; senior investigator at the Howard Hughes Medical Institute.
