A central question in visual neuroscience is what circuits generate the responses of neurons
in the primary visual cortex (V1). V1 neurons respond best to oriented stimuli of optimal size …

It is commonly assumed that the orientation-selective surround field of neurons in primary
visual cortex (V1) is due to interactions provided solely by intrinsic long-range horizontal …

Contrast-dependent changes in spatial summation and contextual modulation of primary
visual cortex (V1) neuron responses to stimulation of their receptive field reveal long …

Iso-orientation surround suppression is a powerful form of visual contextual modulation in
which a stimulus of the preferred orientation of a neuron placed outside the classical …

Vision loss after retinal or cerebral visual injury (CVI) was long considered to be irreversible.
However, there is considerable potential for vision restoration and recovery even in …

The purpose of this chapter is to demonstrate that the study of visual processing
abnormalities in schizophrenia offers a unifying perspective on the etiology, development …

The spiking response of a primary visual cortical cell to a stimulus placed within its receptive
field can be up-and down-regulated by the simultaneous presentation of objects or scenes …

Task-specific improvement in performance after training is well established. The finding that
learning is stimulus-specific and does not transfer well between different stimuli, between …

A broad neuron-centric conception of contextual modulation is reviewed and re-assessed in
the light of recent neurobiological studies of amplification, suppression, and synchronization …

We recorded activity of single units in macaque monkey primary visual cortex (V1) to define
the retinotopic extent of the visual inputs that drive or modulate V1 neuron responses in …
