DOI: 10.1016/j.clinph.2021.01.029
Abstract: OBJECTIVE Motor surround inhibition (mSI) is a physiological mechanism that contributes to hand movement control by focusing voluntary movement. Growing evidence suggests that hand movement control is impaired in multiple sclerosis. The aim of the… read more here.

Surround Integration Organizes a Spatial Map during Active Sensation
Sign Up to like & getrecommendations! Published in 2017 at "Neuron"
DOI: 10.1016/j.neuron.2017.04.026
Abstract: During active sensation, sensors scan space in order to generate a representation of the outside world. However, since spatial coding in sensory systems is typically addressed by measuring receptive fields in a fixed, sensor-based coordinate… read more here.

Phase-specific Surround suppression in Mouse Primary Visual Cortex Correlates with Figure Detection Behavior Based on Phase Discontinuity

DOI: 10.1016/j.neuroscience.2018.03.039
Abstract: In the primary visual cortex (V1), neuronal responses to stimuli within the receptive field (RF) are modulated by stimuli in the RF surround. A common effect of surround modulation is surround suppression, which is dependent… read more here.

DOI: 10.1016/j.visres.2020.07.015
Abstract: A key visual neuronal property that is mirrored in human behaviour is centre-surround contrast suppression, which is orientation-dependent. When a target is embedded in a high-contrast surround, the centre appears reduced in contrast, the magnitude… read more here.

Motion direction tuning in centre-surround suppression of contrast

DOI: 10.1016/j.visres.2020.11.001
Abstract: The perceived contrast of a central stimulus is reduced in the presence of a high contrast surround. A number of stimulus features influence the amount of suppression. A two-mechanism model has been proposed for stationary… read more here.

DOI: 10.1109/tpami.2017.2753239
Abstract: The problem of removing illuminant variations to preserve the colours of objects (colour constancy) has already been solved by the human brain using mechanisms that rely largely on centre-surround computations of local contrast. In this… read more here.

DOI: 10.1167/17.2.13
Abstract: The perceived color of a uniform image patch depends not only on the spectral content of the light that reaches the eye but also on its context. One of the most extensively studied forms of… read more here.

Luminance-contrast properties of texture-shape and texture-surround suppression of contour shape.

DOI: 10.1167/19.12.4
Abstract: Studies have revealed that textures suppress the processing of the shapes of contours they surround. One manifestation of texture-surround suppression is the reduction in the magnitude of adaptation-induced contour-shape aftereffects when the adaptor contour is… read more here.

DOI: 10.1167/jov.21.3.20
Abstract: By attending to part of a visual scene, we can prioritize processing of the most relevant visual information and so use our limited resources effectively. Previous functional magnetic resonance imaging (fMRI) work has shown that… read more here.

DOI: 10.1167/jov.22.2.13
Abstract: Center-surround modulation in visual processing reflects a normalization process of contrast gain control in the responsive neurons. Prior adaptation to a clockwise (CW) tilted grating, for example, leads to the percept of counterclockwise tilt in… read more here.
