The purpose of the study was to examine the density of retinal photoreceptors and retinal pigment epithelium (RPE) cells in relation to myopic axial elongation in human eyes. Using light microscopy, we assessed the density of photoreceptors and RPE cells at the ora serrata, equator, and mid...
Another possibility is that the photoreceptors in the lateral eye contain Ca 2+sensitive K + channels. It has been shown that light... S Levy,A Fein 被引量: 124发表: 0年 Experimental Studies on the Origin of the Cartilage of the Auditory Capsule and Columella in Ambystoma On the basis ...
Macula. The macula is in charge of seeing the fine details of the objects directly in front of you. This may include things like facial details, text on a book or page, and differences between colors. Photoreceptors. Photoreceptor cells are the specific cells within the retina that convert li...
The object image can be reconstructed according to the Fourier spectrum coefficients through inverse Fourier transform with the assistance of the Fourier algorithm. Realizing a 2D image with a single-pixel device in a limited space is a good starting point for intelligent photodetectors, which require...
Miniature eye movements refresh photoreceptors, preventing images from disappearing, as occurs when those images are stabilized on the retina. Miniature eye movements also cause the autokinetic illusion, the tendency to see a single, stationary point of light wander about jerkily in a dark surround. ...
However, zebrafish react most strongly and consistently to lateral, nearly equatorial stimuli, consistent with previously reported higher spatial densities in the central retina of red, green and blue photoreceptors. Upside-down experiments suggest further extra-retinal processing. Our results demonstrate ...
location of such driving oscillations and for the site of the photoreceptors, which mediate entrainment by the environmental light cycle, therefore, occupies a central and important position in the study of insect clocks and one that is relevant to further studies on the mechanisms of clock ...
Methods: Using light microscopy, we counted the density of photoreceptors and RPE cells at the ora serrata, the equator, and at the midpoint between the equator and the posterior pole (MEPP) in enucleated human globes . Results: The study included 78 eyes (mean age: 59.2 ± 15.6 years; ...
We recorded intracellular membrane potential responses from a superfused, sliced preparation of the locust ( Locusta migratoria) eye which allowed localized stimulation of the photoreceptors. The average amplitude of bumps was affected very weakly by stimulus location, in a way which could be accounted...
