To understand the mechanisms underlying visual motion analyses for perceptual and
oculomotor responses and their similarities/differences, we analyzed eye movement …

Two successive image frames presented with a blank inter-stimulus interval (ISI) induce
reversals of perceived motion in humans. This illusory effect is a manifestation of the …

Visual motion signals, which are initially extracted in parallel at multiple spatial frequencies,
are subsequently integrated into a unified motion percept. Cross-frequency integration plays …

Two-frame kinematograms have been extensively used to study motion perception in human
vision. Measurements of the direction-discrimination performance limits (D max) have been …

In addition to motion perception per se, we utilize motion information for a wide range of
brain functions. These varied functions place different demands on the visual system, and …

Global motion and global form are proposed to be processed through functionally
differentiated independent channels along dorsal (motion) and ventral (form) pathways …

A moving random-dot stimulus was presented in two sequential frames separated by an
interstimulus interval (ISI) during which the field was spatially uniform with luminance equal …

Visual images in the real world are spatiotemporally broadband. Yet neurons at the earliest
stages of visual processing respond to stimuli over a limited range of spatial frequencies …

Psychophysical evidence indicates that visual motion can be sensed by low-level (energy-
based) and high-level (feature-based) mechanisms. The present experiments were …

Despite detailed psychophysical, neurophysiological and electrophysiological investigation,
the number and nature of independent and parallel motion processing mechanisms in the …
