Lu Sperling [Vision Res. 35, 2697 (1995)] proposed that human visual motion perception is
served by three separate motion systems: a first-order system that responds to moving …

Recently, neuroimaging techniques have been applied to the study of human motion
perception, complementing established techniques such as psychophysics …

If features such as color and orientation are processed separately by the brain at early
stages 1, 2, how does the brain subsequently match the correct color and orientation? We …

A neural model is developed of how motion integration and segmentation processes, both
within and across apertures, compute global motion percepts. Figure–ground properties …

Naturally occurring visual stimuli are rich in examples of objects delineated from their
backgrounds simply by differences in luminance, so-called first-order stimuli, as well as …

Neurons at progressively higher levels of the visual system have progressively larger, more
complicated receptive fields, presumably constructed from simpler antecedent receptive …

In a two-dimensional display, identical visual targets moving toward and across each other
with equal, constant speed can be perceived either to reverse their motion directions at the …

Visual search rate was used to assess attentional resources required for detection of
opposing motions defined either by luminance or by modulations of texture contrast, flicker …

Since different senses are attuned to the different aspects of the environment, crossmodal
interactions can reduce perceptual ambiguity which may result from relying on a single …

The human visual system contains a functional sub-system that is specialized to extract
image motion. The sensitivities of neurons change as one moves higher in the pathway …
