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

Visual field map clusters in human frontoparietal cortex

open access: yeseLife, 2017
The visual neurosciences have made enormous progress in recent decades, in part because of the ability to drive visual areas by their sensory inputs, allowing researchers to define visual areas reliably across individuals and across species.

Lipid pathway alterations in Parkinson's disease primary visual cortex. [PDF]

open access: yesPLoS ONE, 2011
BackgroundWe present a lipidomics analysis of human Parkinson's disease tissues. We have focused on the primary visual cortex, a region that is devoid of pathological changes and Lewy bodies; and two additional regions, the amygdala and anterior ...

The Visual Cortex in Context

open access: yesAnnual 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.

Connectivity changes underlying neurofeedback training of visual cortex activity.

open access: yesPLoS ONE, 2014
Neurofeedback based on real-time functional magnetic resonance imaging (fMRI) is a new approach that allows training of voluntary control over regionally specific brain activity.

Flexible adjustment of the effective connectivity between the fronto-parietal and visual regions supports cognitive flexibility

open access: yesNeuroImage, 2020
Evidence indicates the significance of the fronto-parietal regions and inertia sensory processing from previous trials in cognitive flexibility. However, how flexible cognitive performance is achieved by causal interactions between cortical regions ...

Why do children with autism spectrum disorder have abnormal visual perception?

open access: yesFrontiers in Psychiatry, 2023
Autism spectrum disorder (ASD) is associated with severe impairment in social functioning. Visual information processing provides nonverbal cues that support social interactions. ASD children exhibit abnormalities in visual orientation, continuous visual

Multi-voxel decoding and the topography of maintained information during visual working memory

open access: yesFrontiers in Systems Neuroscience, 2016
The ability to maintain representations in the absence of external sensory stimulation, such as in working memory, is critical for guiding human behavior.

Paroxetine can improve primary visual cortex activity in a high-risk mouse model of schizophrenia

open access: yesBiotechnology & Biotechnological Equipment, 2020
Visual cortex functional deficits can be observed in schizophrenia patients and in individuals at high risk of schizophrenia. However, to date, few studies have investigated methods to improve these functional deficits.

Auditory attention activates peripheral visual cortex. [PDF]

open access: yesPLoS ONE, 2009
BackgroundRecent neuroimaging studies have revealed that putatively unimodal regions of visual cortex can be activated during auditory tasks in sighted as well as in blind subjects.
