Traveling Waves in Visual Cortex [PDF]
Neuron, 2012 Electrode recordings and imaging studies have revealed that localized visual stimuli elicit waves of activity that travel across primary visual cortex. Traveling waves are present also during spontaneous activity, but they can be greatly reduced by widespread and intensive visual stimulation.

The visual cortex as a crystal [PDF]
Physica D: Nonlinear Phenomena, 2002 A theory of pattern formation in primary visual cortex (V1) is presented that takes into account its crystalline-like structure. The cortex is partitioned into fundamental domains or hypercolumnsof a lattice describing the distribution of singularities or pinwheels in the orientation preference map.

Visual categorization and the parietal cortex [PDF]
Frontiers in Integrative Neuroscience, 2012 The primate brain is adept at rapidly grouping items and events into functional classes, or categories, in order to recognize the significance of stimuli and guide behavior. Higher cognitive functions have traditionally been considered the domain of frontal areas.

Preparatory attention in visual cortex [PDF]
Annals of the New York Academy of Sciences, 2017 Top‐down attention is the mechanism that allows us to selectively process goal‐relevant aspects of a scene while ignoring irrelevant aspects. A large body of research has characterized the effects of attention on neural activity evoked by a visual stimulus. However, attention also includes a preparatory phase before stimulus onset in which the attended

Visual Cortex: Suppression by Depression? [PDF]
Current Biology, 2002 The response of a neuron in the visual cortex to an oriented light bar is strongly reduced by concurrent presentation of a stimulus with a different orientation. New data suggest this 'cross-orientation suppression' is caused, not by intracortical inhibition, but by rapid depression of thalamocortical synapses.

fMRI of Monkey Visual Cortex [PDF]
Neuron, 1998 While functional magnetic resonance imaging (fMRI) is now used widely for demonstrating neural activity-related signals associated with perceptual, motor, and cognitive processes in humans, to date this technique has not been developed for use with nonhuman primates.

Attention: Control in the Visual Cortex [PDF]
Current Biology, 2007 A recent study in which the human visual cortex was directly stimulated to create visual percepts has shown that visual spatial attention can act directly on neural activity in sensory cortex without involving attentional modulation of subcortical visual inputs.

Visual Cortex: Seeing Motion [PDF]
Current Biology, 2003 AbstractHow does primary visual cortex respond to moving images? While much is known about responses of single neurons to such stimuli, responses at the level of maps are only now beginning to be understood.

Annual Review of Vision Science, 2019 In this article, we review the anatomical inputs and outputs to the mouse primary visual cortex, area V1. Our survey of data from the Allen Institute Mouse Connectivity project indicates that mouse V1 is highly interconnected with both cortical and subcortical brain areas.

Sensitivity to syntax in visual cortex [PDF]
Cognition, 2009 One of the most intriguing findings on language comprehension is that violations of syntactic predictions can affect event-related potentials as early as 120 ms, in the same time-window as early sensory processing. This effect, the so-called early left-anterior negativity (ELAN), has been argued to reflect word category access and initial syntactic ...
