Correlation between Feeding Behaviors and Retinal Photoreceptor Cells of Largemouth Bass, Micropterus salmoides, in Korea

Fishes, 2022
The largemouth bass (Micropterus salmoides), a food resource in Korea, is a highly voracious predator, designated as an invasive species. It is both diurnal and nocturnal, with high adaptability and reproducibility.

Functional and behavioral restoration of vision by gene therapy in the guanylate cyclase-1 (GC1) knockout mouse. [PDF]

PLoS ONE, 2010
Recessive mutations in guanylate cyclase-1 (Gucy2d) are associated with severe, early onset Leber congenital amaurosis-1(LCA1). Gucy2d encodes guanylate cyclase (GC1) is expressed in photoreceptor outer segment membranes and produces cGMP in these cells.

Clinical Features of a Pediatric Case with Cone Dystrophy

Van Tıp Dergisi, 2018
The cone dystrophy is a nonhomogenous group of inherited and progressive retinal diseases that affects chiefly the cone system. It is frequently characterized by progressive loss of visual acuity, photophobia, central scotoma, color vision disturbances ...

Visual function and cortical organization in carriers of blue cone monochromacy. [PDF]

PLoS ONE, 2013
Carriers of blue cone monochromacy have fewer cone photoreceptors than normal. Here we examine how this disruption at the level of the retina affects visual function and cortical organization in these individuals.

Attentional Blink Effects on S-Cone Stimuli

i-Perception, 2019
This study aimed to compare attentional blink (AB) effects on S-cone and on luminance stimuli. Recent research had revealed considerable AB effects not only on high-order visual areas but also on low-order visual areas.

Dysflective cones: Visual function and cone reflectivity in long-term follow-up of acute bilateral foveolitis

American Journal of Ophthalmology Case Reports, 2017
Purpose: Confocal adaptive optics scanning laser ophthalmoscope (AOSLO) images provide a sensitive measure of cone structure. However, the relationship between structural findings of diminished cone reflectivity and visual function is unclear.

Resolving single cone inputs to visual receptive fields [PDF]

Nature Neuroscience, 2009
With the current techniques available for mapping receptive fields, it is impossible to resolve the contribution of single cone photoreceptors to the response of central visual neurons. Using adaptive optics to correct for ocular aberrations, we delivered micron-scale spots of light to the receptive field centers of neurons in the macaque lateral ...

Novel rodent models for macular research [PDF]

, 2010
BACKGROUND: Many disabling human retinal disorders involve the central retina, particularly the macula. However, the commonly used rodent models in research, mouse and rat, do not possess a macula.

Asymmetries around the visual field: From retina to cortex to behavior.

PLoS Computational Biology, 2022
Visual performance varies around the visual field. It is best near the fovea compared to the periphery, and at iso-eccentric locations it is best on the horizontal, intermediate on the lower, and poorest on the upper meridian.

Retinal cone photoreceptors of the deer mouse Peromyscus maniculatus : development, topography, opsin expression and spectral tuning

, 2013
A quantitative analysis of photoreceptor properties was performed in the retina of the nocturnal deer mouse, Peromyscus maniculatus, using pigmented (wildtype) and albino animals.
