Magnetic Suppression of Perceptual Accuracy Is Not Reduced in Visual Snow Syndrome

Frontiers in Neurology, 2021
Objective: Patients with visual snow syndrome (VSS) suffer from continuous (“TV snow-like”) visual disturbance of unknown pathoetiology. In VSS, changes in cortical excitability in the primary visual cortex and the visual association cortex are discussed,

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.

Primary visual cortex neurons that contribute to resolve the aperture problem [PDF]

, 2006
It is traditional to believe that neurons in primary visual cortex are sensitive only or principally to stimulation within a spatially restricted receptive field (classical receptive field).

Cross-Modal Functional Reorganization of Visual and Auditory Cortex in Adult Cochlear Implant Users Identified with fNIRS

Neural Plasticity, 2016
Cochlear implant (CI) users show higher auditory-evoked activations in visual cortex and higher visual-evoked activation in auditory cortex compared to normal hearing (NH) controls, reflecting functional reorganization of both visual and auditory ...

Neuron populations across layer 2-6 in the mouse visual cortex exhibit different coding abilities in the awake mice

Frontiers in Cellular Neuroscience, 2023
IntroductionThe visual cortex is a key region in the mouse brain, responsible for processing visual information. Comprised of six distinct layers, each with unique neuronal types and connections, the visual cortex exhibits diverse decoding properties ...

Callosal connections of primary visual cortex predict the spatial spreading of binocular rivalry across the visual hemifields [PDF]

, 2011
In binocular rivalry, presentation of different images to the separate eyes leads to conscious perception alternating between the two possible interpretations every few seconds. During perceptual transitions, a stimulus emerging into dominance can spread

Neural Pathways Conveying Novisual Information to the Visual Cortex

Neural Plasticity, 2013
The visual cortex has been traditionally considered as a stimulus-driven, unimodal system with a hierarchical organization. However, recent animal and human studies have shown that the visual cortex responds to non-visual stimuli, especially in ...

Brief Postnatal Visual Deprivation Triggers Long-Lasting Interactive Structural and Functional Reorganization of the Human Cortex

Frontiers in Medicine, 2021
Patients treated for bilateral congenital cataracts provide a unique model to test the role of early visual input in shaping the development of the human cortex. Previous studies showed that brief early visual deprivation triggers long-lasting changes in

Low-Frequency Local Field Potentials and Spikes in Primary Visual Cortex Convey Independent Visual Information [PDF]

, 2008
Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli.

Computational design and nonlinear dynamics of a recurrent network model of the primary visual cortex. [PDF]

, 2001
Recurrent interactions in the primary visual cortex make its output a complex nonlinear transform of its input. This transform serves preattentive visual segmentation, that is, autonomously processing visual inputs to give outputs that selectively ...
