Characterization of primary visual cortex input to specific cell types in the superior colliculus

Frontiers in Neuroanatomy, 2023
The superior colliculus is a critical brain region involved in processing visual information. It receives visual input directly from the retina, as well as via a projection from primary visual cortex. Here we determine which cell types in the superficial

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

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

PLoS 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 ...

Visual field map clusters in human frontoparietal cortex

eLife, 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.

Connectivity changes underlying neurofeedback training of visual cortex activity.

PLoS 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.

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

Frontiers 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

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

Biotechnology & 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.

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

NeuroImage, 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 ...
