1960 Press Photo Dr. David Nachmansohn announces nerve impulse theory

Dr. David Nachmansohn, M.D., today announced results to support his theory on nerve impulse transmission. He is professor of biochemistry in the Department of Neurology at Columbia University's College of Physicians and Surgeons. He and his staff find that one vital chemical, which generates life electricity in the nerve, acts throughout length of a nerve, not just at nerve endings as scientists had long believed. Findings could aid research in disease in which nerves are responsible.
