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.

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

Optical defocus affects differently ON and OFF visual pathways [PDF]

iScience
Summary: The human eye has a crystalline lens that focuses retinal images at different viewing distances. Optical defocus reduces the spatial resolution and contrast of these retinal images and spectacle lenses minify or magnify their size. Because light

Visual pathways involvement in multiple sclerosis from pathological process to neuro-ophthalmologic assessment [PDF]

Romanian Journal of Neurology, 2014
Multiple sclerosis (MS) is a demyelinating disease associated with a myriad of visual pathways pathology. These pathologies need to be assessed, even when asymptomatic, because they may represent an important index of disease course, severity and ...

The Visually Related Posterior Pretectal Nucleus in the Non-Percomorph Teleost Osteoglossum bicirrhosum Projects to the Hypothalamus [PDF]

, 1991
This study was done to elucidate the ancestral (plesiomorphic) condition for visual pathways to the hypothalamus in teleost fishes. Three patterns of pretectal organization can be discerned morphologically and histochemically in teleosts. Their taxonomic

Distribution of AMPA-type glutamate receptor subunits in the chick visual system

Brazilian Journal of Medical and Biological Research, 1997
Several glutamate receptor (GluR) subunits have been characterized during the past few years. In the present study, subunit-specific antisera were used to determine the distribution of the AMPA-type glutamate receptor subunits GluR1-4 in retinorecipient ...

The Effects of the Müller-Lyer Goalkeepers’ Illusion on Perceptions and Location of Throws of Penalty Takers [PDF]

رشد و یادگیری حرکتی ورزشی, 2019
The main aim of the present study was to investigate whether the goalkeepers’ postures that mimic the Müller–Lyer illusion can influence penalty-takers’ perceptions and the location of throws.

Visual and motor signatures of locomotion dynamically shape a population code for feature detection in Drosophila

eLife, 2022
Natural vision is dynamic: as an animal moves, its visual input changes dramatically. How can the visual system reliably extract local features from an input dominated by self-generated signals?
