Psychophysical studies of interactions between contours defined by different image
attributes report that luminance-defined and illusory contours show little if any interaction …

Neurons in the primary visual cortex respond to oriented stimuli placed in the center of their
receptive field, yet their response is modulated by stimuli outside the receptive field (the …

Adaptation is a multi-faceted phenomenon that is of interest in terms of both its function and
its potential to reveal underlying neural processing. Many behavioral studies have shown …

The tilt aftereffect (TAE) is used to demonstrate the existence of a purely binocular process in
human vision. A purely binocular process is a process that can be activated only by matched …

Sensory adaptation and perceptual learning are two forms of plasticity in the visual system,
with some potential overlapping neural mechanisms and functional benefits. However, they …

The exposure durations of a vertical test line and a tilted inducing grating were varied and
the tilt illusion thus generated was found to change as a function of this variation. Significant …

Discerning objects from their surrounds (ie, figure-ground segmentation) in a way that
guides adaptive behaviors is a fundamental task of the brain. Neurophysiological work has …

Neural oscillations reflect fluctuations in the relative excitation/inhibition of neural systems
and are theorised to play a critical role in several canonical neural computations and …

Conducted 2 experiments on a total of 14 undergraduate Ss to examine the effects of
contrast reversal on the tilt aftereffect (TAE). Exp 1 compared TAE size when both adapting …

We propose that neural grouping of retinotopically distributed responses in the primary
visual cortex (V1) is essential for the determination of apparent tilt, including the tilt illusion …
