Background The human visual system does not treat all parts of an image equally: the
central segments of an image, which fall on the fovea, are processed with a higher …

Using the external noise plus training paradigm, we have consistently found that two
independent mechanisms, stimulus enhancement and external noise exclusion, support …

Detection of motion is a crucial component of visual processing. To probe the computations
underlying motion perception, we created a new class of non-Fourier motion stimuli …

Neural substrates for processing constant speed visual motion have been extensively
studied. Less is known about the brain activity patterns when the target speed changes …

A fundamental goal of visual neuroscience is to identify the neural pathways representing
different image features. It is widely argued that the early stages of these pathways represent …

It is shown that existing processing schemes of 3D motion perception such as interocular
velocity difference, changing disparity over time, as well as joint encoding of motion and …

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 …

The moving observer who looks in the direction of heading experiences radial optic flow,
which is known to elicit horizontal vergence eye movements at short latency, expansion …

A version of the line motion illusion (LMI) occurs when one of two adjacent surfaces changes
in luminance; a new surface is perceived sliding in front of the initially presented surface …

Perceptual learning was used as a tool for studying motion perception. The pattern of
transfer of learning of luminance-(LM) and contrast-modulated (CM) motion is diagnostic of …
