Not exact matches

By comparing how fast the neural circuits in the retina perform image - processing operations with how many instructions per second it takes a computer to accomplish similar work, I believe it is possible to at least coarsely estimate the information - processing power of nervous tissue — and by extrapolation, that of the entire human nervous system.

To find out Reppert replaced those found in fruit flies with a human version, hCRY2, which is found in the retina.

The question that carried him from vision research to autism had to do with what happens after light hits the human retina: How are the incoming signals transformed into data that are ultimately processed as images in the brain?

When retinal cells die they are much more likely to die in the center of the retina than in the periphery, which the researchers say is exactly what happens in humans with age and the problem with macular degeneration.

In human clinical trials with Euclidean - based devices, visual acuity has only achieved 20/1260 for implants placed in front of the retina.

To precisely map how glucose and lactate move around in the eye, Hurley and colleagues grew human RPE in a lab dish and studied its biochemistry along with that of isolated mouse retinas.

Just like humans, monkeys are occasionally born with a defective gene that is responsible for some of the color receptors in their retinas, leaving them red — green color - blind.

Canadian Institute for Advanced Research senior fellows Brian Leander and Patrick Keeling supervised lead author Greg Gavelis at the University of British Columbia and, in collaboration with senior fellow Curtis Suttle, showed that this eye - like structure contains a collection of sub-cellular organelles that look very much like the lens, cornea, iris and retina of multicellular eyes that can detect objects — known as camera eyes — that are found in humans and other larger animals.

Confocal images of P150 dystrophic retina transplanted with hNPCctx — GDNF and double stained with antibodies against human nuclear antigen (red) and either (A) recoverin, a photoreceptor and cone bipolar cell marker (green), or (B) protein kinase Cα (PKCα), a bipolar cell marker (green).

One of the results of this collaboration is that we were able to take a basic science finding from Andrew Huberman's lab that certain layers in the retina are affected early in glaucoma — and we're immediately able to develop engineering approaches to see some of those changes in human patients with glaucoma.

(C) Confocal image of P150 dystrophic inner retina transplanted with hNPCctx — GDNF and double stained with antibodies against nestin, a neural stem and progenitor cell marker (green) and human nuclear antigen (red).

We've been able to bridge those findings to human studies, developing ways to both look for those neurons in the retina, see whether or not they're sick using imaging techniques that Alf and Vivek have developed, and clinical tests along with Jeff Goldberg in order to detect whether or not patients are losing an excessive amount of those kinds of neurons by virtue of different types of field testing.

The published paper concluded that» «molecular alterations detected in the ocular hypertensive human retina as opposed to previously detected alterations in human donor retinas with clinically manifest glaucoma suggest that proteome alterations determine the individual threshold to tolerate the ocular hypertension - induced tissue stress or convert to glaucomatous neurodegeneration when intrinsic adaptive / protective responses are overwhelmed.»

Together with another long - chain polyunsaturated fatty acid called arachidonic acid (a member of the omega - 6 family), it makes up 30 % of the phospholipid content of the human brain and retina (source).

In mid-2010 with the release of the iPhone 4, Apple introduced us to a new concept — the «Retina display,» so called because the screen was packed tightly with so many pixels that the dots would be imperceptible to the human eye.

(Human boxers sometimes wind up with detached retinas.)

Waardenburg's syndrome, a human condition, presents with deafness, a stripe of white in the hair and beard, blue or different colored eyes (even in Blacks and Asians), no pigment behind the retina, and minor structural deformities around the nose and eyes.

Like with human cataracts, dogs develop a cloudy white or gray film over the center of their eyes, just behind the retina.

To further examine the morphology of cells and the localization of protein expression within the retina, immunohistochemical staining of both paraffin and OCT retinal sections was performed with the following antibodies (Table S1): human cone arrestin (for cone photoreceptors), rhodopsin (for rod photoreceptors), RPE65 (for the retinal pigment epithelium, RPE), glial fibrillary acidic protein (GFAP, for astrocytes and Müller cells), glutamine synthetase (for Müller cells) and G0alpha (for ON bipolar cells).

In young affected dogs retinal structure, rhodopsin expression and photoreceptor activation is normal; disease progression is characterized by regions of initial focal photoreceptor degeneration surrounded by areas of structurally normal retina, which interestingly is very similar to the phenotypes of humans with RHO mutations [24].

The crystal clear Quad HD, which means: 2,560 x 1,440 Resolution, 577ppi Pixel Density, and a phenomenal sharp display with rich and deep black colours, paired with the flexible SuperAMOLED display is simply stunning and absolutely outstrips the iPhone 6S that is known to have Retina, the highest resolution that can be perceived by humans.
