The effect of spatial configuration on surround suppression of contrast sensitivity.
Contrast sensitivity is known to be strongly influenced by the target surround, yet the role of the surround interaction in visual processing remains unclear. Previously, we have shown that the surround strongly suppresses contrast sensitivity in the periphery when the surround spatial frequency and orientation match those of the target (Petrov, Carandini, & McKee, 2005). Here, we explore how v...
متن کاملSurround Suppression and Recurrent Interactions V1-V2 for Natural Scene Boundary Detection
Understanding the brain functioning in visual process is one of the more active areas within neuroscience, modeling and computation. This great interest is due to the fact that vision provides us with the more important information about the surroundings. Oriented early filtering processes, perceptual clustering through emerging features, form and depth perception, figure-ground separation, and...
متن کاملMigraine Increases Centre-Surround Suppression for Drifting Visual Stimuli
BACKGROUND The pathophysiology of migraine is incompletely understood, but evidence points to hyper-responsivity of cortical neurons being a key feature. The basis of hyper-responsiveness is not clear, with an excitability imbalance potentially arising from either reduced inhibition or increased excitation. In this study, we measure centre-surround contrast suppression in people with migraine a...
متن کاملModeling grating contrast discrimination dippers: The role of surround suppression.
We consider the role of nonlinear inhibition in physiologically realistic multineuronal models of V1 to predict the dipper functions from contrast discrimination experiments with sinusoidal gratings of different geometries. The dip in dipper functions has been attributed to an expansive transducer function, which itself is attributed to two nonlinear inhibitory mechanisms: contrast normalizatio...
متن کاملCortical Surround Interactions and Perceptual Salience via Natural Scene Statistics
Spatial context in images induces perceptual phenomena associated with salience and modulates the responses of neurons in primary visual cortex (V1). However, the computational and ecological principles underlying contextual effects are incompletely understood. We introduce a model of natural images that includes grouping and segmentation of neighboring features based on their joint statistics,...
