In the retina, the receptive field surround preserves the spatial contrast sensitivity of the center in the face of naturalistic changes in local luminance.
Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.
Anatomical and physiological analyses identified an inhibitory interneuron that is an integral part of the rod bipolar cell pathway, the circuit for night vision, of the mammalian retina.
The paradoxical spatial suppression of visual motion perception can result from a trade-off between sensitivity and noise in sensory neuron populations.
There is a systematic functional organization for curvature representation in area V4 where specific curvatures are encoded by unique values (modules) from the set of systematically represented values.
To see the world stable across saccades, the brain compensates retinal shifts induced by the movements, pre-saccadic maps of sensitivity reveal that this process takes time and follows attentional dynamics.
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.
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.
Functional MRI measurements of orientation reflect coarse-scale biases that are wholly determined by second-order interactions between the stimulus aperture and the underlying orientation.
