Surround inhibition is a neural mechanism that assists in the focusing of excitatory drive to
muscles responsible for a given movement (agonist muscles) by suppressing unwanted …

Contextual effects abound in the real world; how we perceive an object depends on what
surrounds it. A classic example of this is the tilt illusion (TI) whereby the presence of a …

Adaptation in the visual system frequently results in properties of subsequently presented
stimuli being repelled along identifiable axes. Adaptation to radial frequency (RF) patterns …

We investigated the functional changes in short intracortical inhibitory (SICI) circuits to
determine whether surround inhibition is altered during a simple finger movement training …

Binocular rivalry is an intriguing phenomenon: when different images are displayed to the
two eyes, perception alternates between these two images. What determines whether two …

In classic geometric illusions such as the Zollner illusion, vertical lines superimposed on
oriented background lines appear tilted in the direction opposite to the background. In …

The apparent contrast of a texture is reduced when surrounded by another texture with high
contrast. This contrast–contrast phenomenon has been thought to be a result of spatial …

Since its conception, the Poggendorff Figure has always been studied by considering the
absolute role of the variables involved in determining the illusion (eg the angle or the …

The direction illusion is the phenomenal exaggeration of the angle between the drift
directions, typically, of two superimposed sets of random dots. The direction illusion is …

To interpret visual scenes, visual systems need to segment or integrate multiple moving
features into distinct objects or surfaces. Previous studies have found that the perceived …
