Cathodal Occipital tDCS is unable to modulate The Sound Induced Flash Illusion in migraine [PDF]

open access: yes, 2019
Migraine is a highly disabling disease characterized by recurrent pain.Despite an intensive effort, mechanisms of migraine pathophysiology, still represent an unsolved issue.

Visual categorization and the parietal cortex [PDF]

open access: yesFrontiers 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.

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

open access: yesNeural 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 ...

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

open access: yesFrontiers 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

Neural correlates of motion-induced blindness in the human brain [PDF]

open access: yes, 2010
Motion-induced blindness (MIB) is a visual phenomenon in which highly salient visual targets spontaneously disappear from visual awareness (and subsequently reappear) when superimposed on a moving background of distracters. Such fluctuations in awareness

Neural Pathways Conveying Novisual Information to the Visual Cortex

open access: yesNeural 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 ...

Organization of the dorsal lateral geniculate nucleus in the mouse [PDF]

open access: yes, 2017
The dorsal lateral geniculate nucleus (dLGN) of the thalamus is the principal conduit for visual information from retina to visual cortex. Viewed initially as a simple relay, recent studies in the mouse reveal far greater complexity in the way input from

Preparatory attention in visual cortex [PDF]

open access: yesAnnals 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

Eye position representation in human anterior parietal cortex [PDF]

open access: yes, 2008
Eye position helps locate visual targets relative to one's own body and modulates the distribution of attention in visual space. Whereas in the monkey, proprioceptive eye position signals have been recorded in the somatosensory cortex, in humans, no ...

Visual Cortex: Suppression by Depression? [PDF]

open access: yesCurrent 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.
