John Olney is a medical doctor and a professor of psychiatry, pathology, and immunology at the Washington University School of Medicine. He is known for his work on brain damage. He coined the term excitotoxicity in his 1969 paper published in Science. Olney's lesions are named after him. In 1996 he was elected to the Institute of Medicine of the United States National Academy of Sciences. He has campaigned for greater regulation of monosodium glutamate (MSG), aspartame and other excitotoxins for over twenty years.
