Abstract

Recent studies in psychophysics and neurophysiology suggest that the human visual system utilizes a range of different size or spatial frequency tuned mechanisms in its processing of visual information. It has been proposed that there exist four such mechanisms. This note argues that there exists indirect evidence for the existence of a fifth, smaller channel.
