Abstract : The properties of the evoked activity of the electroretinogram and two other optic tract potentials were studied in the time and frequency domains. Digital filtering techniques are used to determine the effects of recording equipment frequency response of the various characteristics of the signals. A decomposition algorithm to fractionate the observed waveforms into their physiologically significant components is developed. It is based on findings reported in the literature and the results of some controlled experiments. The technique is applied to the problem of detecting and evaluating retinal injury. (Author)
