Visual motion gradient sensitivity shows scale invariant spatial frequency and speed tuning properties
We investigated sensitivity to motion gradients psychophysically using a band-pass filtered white noise stimulus with two superimposed components moving in opposite directions and spatially modulated with out of phase periodic functions. An optimum sensitivity ratio of the carrier to the modulator frequency of about 11 was measured. Tuning for speed was also observed, with sensitivity falling o...
متن کاملVisual adaptation reveals asymmetric spatial frequency tuning for motion.
This study investigated the spatial frequency selectivity of the human visual motion system using the technique of adaptation in which motion aftereffect (MAE) duration was taken as an index of aftereffect magnitude. Eight observers adapted to two vertically oriented, oppositely drifting, luminance-defined gratings that were spatially separated in the vertical dimension. The spatial frequency o...
متن کاملSpatial-frequency tuning of visual contour integration.
We examine the mechanism that subserves visual contour detection and particularly its tuning for the spatial frequency of contour components. We measured the detection of contours composed of Gabor micropatterns within a field of randomly oriented distractor elements. Distractors were randomly assigned one of two spatial frequencies, and elements lying along the contour alternated between these...
متن کاملTemporal and Spatial Frequency Tuning of the Flicker Motion Aftereffect
The motion aftereffect (MAE) was used to study the temporal and spatial frequency selectivity of the visual system at supra-threshold contrasts. Observers adapted to drifting sine-wave gratings of a range of spatial and temporal frequencies. The magnitude of the MAE induced by the adaptation was measured with counterphasing test gratings of a variety of spatial and temporal frequencies. Indepen...
متن کاملGamma Frequency and the Spatial Tuning of Primary Visual Cortex
Visual stimulation produces oscillatory gamma responses in human primary visual cortex (V1) that also relate to visual perception. We have shown previously that peak gamma frequency positively correlates with central V1 cortical surface area. We hypothesized that people with larger V1 would have smaller receptive fields and that receptive field size, not V1 area, might explain this relationship...
