Early and Late Mechanisms of Surround Suppression in Striate Cortex of Macaque
The response of a neuron in striate cortex to an optimally configured visual stimulus is generally reduced when the stimulus is enlarged to encroach on a suppressive region that surrounds itsExpand

Feedback from V1 and inhibition from beyond the classical receptive field modulates the responses of neurons in the primate lateral geniculate nucleus
It is well established that the responses of neurons in the lateral geniculate nucleus (LGN) can be modulated by feedback from visual cortex, but it is still unclear how cortico-geniculate afferentsExpand

The nature of V1 neural responses to 2D moving patterns depends on receptive-field structure in the marmoset monkey.
A plaid pattern is formed when two sinusoidal gratings of different orientations are added together. Previous work has shown that V1 neurons selectively encode the direction and orientation of theExpand

Perceptual Learning Reduces Crowding in Amblyopia and in the Normal Periphery
Amblyopia is a developmental visual disorder of cortical origin, characterized by crowding and poor acuity in central vision of the affected eye. Crowding refers to the adverse effects of surroundingExpand

Spatial distribution of suppressive signals outside the classical receptive field in lateral geniculate nucleus.
A suppressive surround modulates the responsiveness of cells in the lateral geniculate nucleus (LGN), but we know nothing of its spatial structure or the way in which it combines signals arising fromExpand

Transfer of perceptual learning between different visual tasks.
Practice in most sensory tasks substantially improves perceptual performance. A hallmark of this 'perceptual learning' is its specificity for the basic attributes of the trained stimulus and task.Expand

Recovery of stereo acuity in adults with amblyopia
Disruption of visual input to one eye during early development leads to marked functional impairments of vision, commonly referred to as amblyopia. A major consequence of amblyopia is the inabilityExpand

The pattern of learned visual improvements in adult amblyopia.
PURPOSE Although amblyopia is diagnosed in terms of a monocular letter acuity loss, individuals typically present with deficits on a wide range of spatial tasks. Many of these deficits can beExpand

Gain control from beyond the classical receptive field in primate primary visual cortex
Gain control is a salient feature of information processing throughout the visual system. Heeger (1991, 1992) described a mechanism that could underpin gain control in primary visual cortex (V1).Expand
