Abstract

Detection of aliasing varies throughout the peripheral visual field in a systematic way we call radial tuning; the cutoff spatial frequency is always maximized when the grating is oriented radially.¹ Because this orientational anisotropy occurs for grating stimuli produced as interference fringes directly on the retina with an achromatic interferometer, we suggested previously that radial tuning is of neural, not optical, origin. New theoretical analysis has caused us to reconsider the basis of radial tuning.
