Neural Conduction Along Postretinal Visual Pathways in Glaucoma [PDF]
Frontiers in Aging Neuroscience, 2021 Purpose: This study was conducted in order to evaluate retinal ganglion cell (RCG) function and the neural conduction along the postretinal large and small axons and its correlation with retinal nerve fiber layer thickness (RNFL-T) in open-angle glaucoma

Dynamics of Visual Adaptation With Simultaneous Stimulation of Two Visual Pathways [PDF]
Frontiers in Neuroscience, 2021 Primates’ retinal ganglion cells in different visual pathways have been shown to adapt independently (Current Biology 22 (2012) 220–224). However, the manner in which adaptation occurs under simultaneous stimulation of two visual pathways has not yet ...

3.0 T multi-parametric MRI reveals metabolic and microstructural abnormalities in the posterior visual pathways in patients with thyroid eye disease [PDF]
Frontiers in Neuroscience, 2023 IntroductionWe aim to explore the microstructural and metabolic changes in visual pathways in patients with thyroid eye disease (TED) using 3T multi-parametric MRI.MethodsThirty-four TED patients (inactive group = 20; active group = 14; acute group = 18;

Morphometric analyses of the visual pathways in macular degeneration [PDF]
, 2015 Introduction. Macular degeneration (MD) causes central visual field loss. When field defects occur in both eyes and overlap, parts of the visual pathways are no longer stimulated. Previous reports have shown that this affects the grey matter of the primary visual cortex, but possible effects on the preceding visual pathway structures have not been ...

Role of glutamate in the development of visual pathways [PDF]
Frontiers in Ophthalmology, 2023 Glutamate is an important amino acid, metabolite and excitatory neurotransmitter, which is found in its free form in the extracellular spaces of the central nervous system (CNS). More than half of all synapses in CNS release glutamate.

Neural pathways for visual speech perception [PDF]
Frontiers in Neuroscience, 2014 This paper examines the questions, what levels of speech can be perceived visually, and how is visual speech represented by the brain? Review of the literature leads to the conclusions that every level of psycholinguistic speech structure (i.e., phonetic

Retinal and Visual Pathways Involvement in Carriers of Friedreich’s Ataxia [PDF]
Diagnostics, 2022 Friedreich’s ataxia (FRDA) is a rare autosomal recessive neurodegenerative disorder due to the homozygous pathological expansion of guanine-adenine-adenine (GAA) triplet repeats in the first intron of the FXN gene, which encodes for the mitochondrial ...

I'll take the low road: The evolutionary underpinnings of visually triggered fear. [PDF]
Frontiers in Neuroscience, 2015 Although there is general agreement that the central nucleus of the amygdala (CeA) is critical for triggering the neuroendocrine response to visual threats, there is uncertainty about the role of subcortical visual pathways in this process.

Wiring the Binocular Visual Pathways [PDF]
International Journal of Molecular Sciences, 2019 Retinal ganglion cells (RGCs) extend axons out of the retina to transmit visual information to the brain. These connections are established during development through the navigation of RGC axons along a relatively long, stereotypical pathway. RGC axons exit the eye at the optic disc and extend along the optic nerves to the ventral midline of the brain,

Dissociated modulations of multivoxel activation patterns in the ventral and dorsal visual pathways by the temporal dynamics of stimuli [PDF]
Brain and Behavior, 2020 Introduction Previous studies suggested temporal limitations of visual object identification in the ventral pathway. Moreover, multivoxel pattern analyses (MVPA) of fMRI activation have shown reliable encoding of various object categories including faces
