Analog simulation for spatio-temporal characteristics of visual system

In this paper, the function of visual system was mainly analysed by spatio-temperal characteristics based upon Enroth´s model, Broca-Sulzer phenomenon and Mach effect. (a) In order to get the excitatory and inhibitory potential of intermediate cell layer in the retina, the exponential value exp {(FM/kT)-Imn} was calculated based on the physiological theory in neuro-phenomena. (b) To show the visual characteristics by the analog simulation for generating stimulus waveforms and analysis, the visual adaptation was recorded as electrical stimulation in the form of step functions. Furthermore, it was shown that there was a satisfactory agreement within experimental errors between those data obtained and the theoretical values, which is psycho-physiological.
