Abstract : Several investigations have been conducted on the pattern recognition capability of a proposed model of the visual cortex. This investigation is aimed at determining the internal relationships existing within the model. Special emphasis is placed on the formation of memory patterns during the 'learning' process. A model is developed which enables the investigation of single inputs unhampered, in most cases, by the limitation of array size. The effects of coupling on the spatial distribution of the memory patterns are investigated. In addition, the transient and stability effects are investigated from the standpoint of computer operation time. An attempt is made to correlate the memory patterns with one case of Fraunhofer diffraction. As a result of the background research into the human visual system, a proposal is made for considering the eye as a diffracting, rather than an imaging, device. An experiment is also suggested which may isolate possible sub-channels within the visual channel, which may be concerned with the transmission of color information. (Author)
