The main purpose of this work is to create a physiologically realistic computational model of the retina by providing a flexible, real-valued three-dimensional architecture. This model exhibits the overall spatio-temporal response of the network as a whole, as well as the temporal responses of individual cells in the different layers of the retina. The network performs both functions in a consistent way. The model will be expanded in the near future to include color vision, Mach Band effects. It can also be used to model other physiological systems and functions. The platform on which this neural network is built is Windows 98 using an object oriented approach.
