Sentences with phrase «nerve cells in the retina»

The researchers identified a transcription factor called POU6F2, which is found in developing nerve cells in the retina and corneal cells in mice.

Not exact matches

Anatomical investigations have shown, however, that there are many more receptor cells in the retina than there are fibers in the optic nerve.

These electrodes pulse to stimulate cells in the retina, transmitting visual information along the optic nerve to the brain, creating the perception of patterns of light.

The impulse starts with excitation of the left retina, then travels down the optic nerve to cells in the midbrain and brain stem, which excite neurons near both eyes that cause the pupils to constrict.

When these photoreceptors detect light, they send a signal to specialized neurons in the retina called retinal ganglion cells, or RGCs, which then transmit visual information to the brain by firing electrical pulses along the optic nerve.

In vertebrates, nerve cells called retinal ganglion cells send information from the retina to vision - processing centers in the braiIn vertebrates, nerve cells called retinal ganglion cells send information from the retina to vision - processing centers in the braiin the brain.

When a rod cell in the retina absorbs light, a cascade of reactions results in a nerve signal.

Methanol harms sight mainly by damaging mitochondria in cells in the eye's retina and optic nerve.

Their focus is the retina, the thin tissue in the back of the eye containing the photoreceptors and nerve cells.

In fact, so much of the progress that we're making in laboratories, including mine, is on developing neuroprotective therapies that can protect the retina from degeneration, regenerate optic nerve fibers all the way back to their targets in the brain, and even replace damaged retinal ganglion cells with self - therapies that completely rebuild the optic nervIn fact, so much of the progress that we're making in laboratories, including mine, is on developing neuroprotective therapies that can protect the retina from degeneration, regenerate optic nerve fibers all the way back to their targets in the brain, and even replace damaged retinal ganglion cells with self - therapies that completely rebuild the optic nervin laboratories, including mine, is on developing neuroprotective therapies that can protect the retina from degeneration, regenerate optic nerve fibers all the way back to their targets in the brain, and even replace damaged retinal ganglion cells with self - therapies that completely rebuild the optic nervin the brain, and even replace damaged retinal ganglion cells with self - therapies that completely rebuild the optic nerve.

Imagine how difficult it is for a patient and their family and friends when they lose vision, as is the case in a disorder such as age - related macular degeneration (AMD), where the unexpected sprouting of weak and leaky new blood vessels leads to death the ath of the nerve cells of the retina.

On the surface, the disease appears relatively simple, with high pressure (intra-ocular pressure, or IOP) within the eye associated with the death of cells in the retina and optic nerve dysfunction.

But biopsying tumors in the retina, the thin layer of nerve cells in the back of the eye, risks spreading cancer by unleashing tumor particles into the rest of the body and the brain.
