    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.

    Attention operates uniformly throughout the classical receptive field and the surround

    Bram-Ernst Verhoef, John HR Maunsell
    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.

    Distinct spatiotemporal mechanisms underlie extra-classical receptive field modulation in macaque V1 microcircuits

    Christopher A Henry et al.
    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.

    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.

    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.

    Suppression and facilitation of human neural responses

    Michael-Paul Schallmo et al.
    Spatial suppression during motion perception reflects reduced neural response magnitudes in visual areas but is not primarily driven by neural inhibition.

    A predictive focus of gain modulation encodes target trajectories in insect vision

    Steven D Wiederman et al.
    Visual neurons in the dragonfly predict the path of a moving target, even when it is occluded or crosses from one eye to the other.

    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.

    Processing of motion boundary orientation in macaque V2

    Heng Ma et al.
    Area V2 in macaque monkeys contributes to the perception of the outlines of moving objects and achieves this through a local computation.

    A model for focal seizure onset, propagation, evolution, and progression

    Jyun-you Liou et al.
    Usage-dependent inhibition breakdown and neural adaptation underpins the key spatiotemporal dynamics of human focal seizures.
