PROPOSED COMPUTATIONS IN THE CEREBRAL CORTEX BASED ON FOURIER TRANSFORM AND SPATIAL FILTERING TECHNIQUES

摘要

This paper employs some recent findings in the field of optics to postulate the nature of the cortical calculation. To show this, a mathematical formulation of an optical transform is discussed. A laser is used to experimentally obtain this transform. The properties of the transform are then investigated. The optical theory is compared with a specified cortical connectivity to model a basic computational cell. An array of these cells are shown to duplicate a transform process similar to the optical transform process. The calculation performed by the array is then simulated on the IBM 7094 computer for various input patterns.
