    Receptive field center-surround interactions mediate context-dependent spatial contrast encoding in the retina

    Maxwell H Turner et al.
    In the retina, the receptive field surround preserves the spatial contrast sensitivity of the center in the face of naturalistic changes in local luminance.

    Surface color and predictability determine contextual modulation of V1 firing and gamma oscillations

    Alina Peter et al.
    Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.

    Connectomic analysis reveals an interneuron with an integral role in the retinal circuit for night vision

    Silvia JH Park et al.
    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.

    A neural basis for the spatial suppression of visual motion perception

    Liu D Liu et al.
    The paradoxical spatial suppression of visual motion perception can result from a trade-off between sensitivity and noise in sensory neuron populations.

    Curvature domains in V4 of macaque monkey

    Jia Ming Hu et al.
    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.

    Pre-saccadic remapping relies on dynamics of spatial attention

    Martin Szinte et al.
    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.

    Bidirectional encoding of motion contrast in the mouse superior colliculus

    Jad Barchini et al.
    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-processing domains in primate V4

    Rendong Tang et al.
    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.

    Selectivity to approaching motion in retinal inputs to the dorsal visual pathway

    Todd R Appleby, Michael B Manookin
    Cells in the primate retina show unexpected sensitivity to approaching motion and optical flow.

    Stimulus vignetting and orientation selectivity in human visual cortex

    Zvi N Roth et al.
    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.
