McCulloch, Warren Sturgis (1899–1969)

US neurophysiologist who developed cybernetic and computational models of the brain. His papers include ‘What the Frog's Eye Tells the Frog's Brain’ 1959, which detailed the way in which information is transmitted from the retina to the brain to detect significant features or events in the frog's environment.

McCulloch was born in Orange, New Jersey, and educated at Yale and Columbia. His initial work, conducted at Yale in the 1930s, concentrated on primate physiology; his work on brain models was undertaken initially at the University of Illinois and later, from 1952, at the Massachusetts Institute of Technology.
