Abstract

One advantage of evoked potentials (EPs) to transient stimuli is that they contain information as to the time-course of the electrophysiological response to such stimuli. This time course may be presumed to reflect the temporal sequence in which information contained in the stimulus is processed. The present paper is primarily directed toward a better understanding of the time course of information processing specific to the size (spatial frequency) and orientation of the elements of visual stimuli. Such processing will be considered both in relationship to sensory information channels and selective attention. The final section will be a brief review of preliminary data on the potential applications of these types of procedures to clinical problems.
