Warren Sturgis McCulloch (November 16, 1898 – September 24, 1969) was an American neurophysiologist and cybernetician, known for his work on the foundation for certain brain theories and his contribution to the
Biography
Warren Sturgis McCulloch was born in
In 1941 he moved to Chicago and joined the Department of Psychiatry at the
McCulloch had a range of interests and talents. In addition to his scientific contributions he wrote poetry (
McCulloch married Ruth Metzger, known as 'Rook', in 1924 and they had three children.[6] He died in Cambridge in 1969.
Work
He is remembered for his work with Joannes Gregorius Dusser de Barenne from Yale[7] and later with Walter Pitts from the University of Chicago. He provided the foundation for certain brain theories in a number of classic papers, including "A Logical Calculus of the Ideas Immanent in Nervous Activity" (1943) and "How We Know Universals: The Perception of Auditory and Visual Forms" (1947), both published in the Bulletin of Mathematical Biophysics. The former is "widely credited with being a seminal contribution to neural network theory, the theory of automata, the theory of computation, and cybernetics".[1]
McCulloch was the chair of the set of Macy conferences dedicated to Cybernetics. These, greatly due to the diversity of the backgrounds of the participants McCulloch brought in, became the foundation for the field.
Neural network modelling
In the 1943 paper McCulloch and Pitts attempted to demonstrate that a Turing machine program could be implemented in a finite network of formal neurons (in the event, the Turing Machine contains their model of the brain, but the converse is not true[8]), that the neuron was the base logic unit of the brain. In the 1947 paper they offered approaches to designing "nervous nets" to recognize visual inputs despite changes in orientation or size.
From 1952 McCulloch worked at the Research Laboratory of Electronics at MIT, working primarily on neural network modelling. His team examined the visual system of the frog in consideration of McCulloch's 1947 paper, discovering that the eye provides the brain with information that is already, to a degree, organized and interpreted, instead of simply transmitting an image.
Reticular formation
McCulloch also posited the concept of "poker chip"
