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 cybernetics movement.
Neural network modelling
In the 1943 paper they 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) 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 he 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.
McCulloch also posited the concept of “poker chip” reticular formations as to how the brain deals with contradictory information in a democratic, somatotopical neural network. His principle of “Redundancy of Potential Command” was developed by von Forster and Pask in their study of Self-organization.
