Adapting neurons at early stages of cortical visual processing to an oriented grating pattern
suppresses responses to nearby orientations, causing a shift in the population response to …

Adaptation to prevailing stimuli is a ubiquitous property of the visual system that optimizes its
dynamic range. The perceived difference in orientation of successively presented lines of …

Integration of multiple properties of an object is a fundamental function of the visual cortex in
object recognition. For instance, surface patterns and contour shapes are thought to be …

Recent physiological studies revealed that neurons in the macaque visual cortex encode the
direction of a figure along a contour (border ownership, BO). Although their cortical …

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

Contextual effects abound in vision. The tilt illusion (TI) is an example—a tilted surrounding
annulus causes a vertical central pattern to appear rotated away from the surround. We …

Following monocular adaptation to a grating tilted 10° clockwise from the vertical, subjects
judged the orientation of a single bar tilted 1–7° clockwise from the vertical presented …

Human perceptual ability can be improved by perceptual learning through repeated
exposure or training. Perceptual learning studies have focused on achieving accurate …

Four experiments in which logarithmic intervals between 25 and 1600 ms were used for
stimulus duration in tests for the tilt illusion are reported. It is demonstrated that the direct and …

RF-LISSOM, a self-organizing model of laterally connected orientation maps in the primary
visual cortex, was used to study the psychological phenomenon known as the tilt aftereffect …
