Electrophysiological indexes of illusory contours perception in humans.

The present study investigated brain mechanisms underlying the perception of illusory contours, using recordings of event-related potentials of the brain (ERPs) in right-handed individuals. Forty different stimuli were presented randomly 1600 times in foveal vision; twenty of them produced the perception of illusory contours of a Kanizsa square, the remaining were obtained rotating outwards the...

Equivalent representation of real and illusory contours in macaque V4.

The cortical processing of illusory contours provides a unique window for exploring the brain mechanisms underlying visual perception. Previous electrophysiological single-cell recordings demonstrate that a subgroup of cells in macaque V1 and V2 signal the presence of illusory contours, whereas recent human brain imaging studies reveal higher-order visual cortices playing a central role in illu...

Young infants' perception of illusory contours in dynamic displays.

Ninety-six 4-month-old infants were habituated to one of three computer-generated displays depicting two rod parts above and below an occluding box. In the first display, the surfaces and boundaries of the rod and box were specified by dense surface texture. Their depth segregation was specified by accretion and deletion of background texture and motion shear. In the second display, the unity o...

Illusory surface perception and visual organization.

Illusory contours occur in a wide variety of circumstances in nature. A striking man- made example is the Kanizsa triangle. A common factor in all such figures is the perception of a surface occluding part of a background, i.e. illusory contours are always accompanied by illusory surfaces. The detection of occlusion cues suggest various different local surface configurations, leading to a large...

Illusory contours

Illusory contours are perceived in the absence of any real physical luminance gradients between inducers that are spatially discontinuous (Fig. 1a,b).1–3 It has been controversial whether the perception of these subjective contours arise from higher level cognitive mechanisms that depend on attention and serial search4–6 or from lower level parallel processing in the early automatic, preattenti...
