A spatially-tuned normalization model accounts for neuronal responses to attended or unattended stimuli that are presented inside the classical receptive field or the surround, and explains various other observations.
The paradoxical spatial suppression of visual motion perception can result from a trade-off between sensitivity and noise in sensory neuron populations.
Two photon calcium imaging experiments show that excitatory and inhibitory neurons in the mouse superior colliculus are differentially modulated by the motion contrast between stimulus center and surround.

Spatial suppression during motion perception reflects reduced neural response magnitudes in visual areas but is not primarily driven by neural inhibition.

The multiple component mechanisms of extra-classical receptive field modulation, with distinct dynamics, discovered in the monkey visual cortex have important implications for understanding contextual perceptual processing.

Neurons responsible for detecting local visual features are modulated by visual and motor-related forms of gain control that increase the threshold for detection when self-generated movement signals would dominate visual input.
Curvature-preferring neurons in monkey V4 cluster into 0.5-mm patches, which highlights the importance of curvature detection in visual object recognition and the key functional role of V4 in this process.
Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.
