The macula is densely packed with photoreceptor cells called rods and cones that react to light and send electrical nerve impulses to the optic nerve and into the brain.

The retina contains small, specialized neurons called bipolar cells that transmit information from light - sensitive photoreceptor cells to ganglion neurons, which send information to the brain for interpretation as images.
Nevertheless, the outcome may pave the way for transplants of stem cell — derived eye cells called photoreceptors, which could dramatically improve vision in people with eye disease if all goes according to plan.
In the new study, the team focused on neurons called amacrine cells and horizontal cells, which have a known role in «preprocessing» — or adjusting — electrical signals transmitted to the brain from the photoreceptors after they have been stimulated by light photons.
It first targets a protective lining called the retinal pigment epithelium (RPE), which shuttles nutrients to the photoreceptor cells and is vital for their survival.
A new gene therapy treatment has restored some sight in a handful of blind patients suffering from Leber's congenital amaurosis, a syndrome in which, because of a broken or missing gene called RPE65, retinal photoreceptor cells malfunction and eventually die.
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.
A healthy retina usually features light - sensitive cells — photoreceptors — called cones and rods.
After years of searching hard for the so - called photoreceptor cells that relay that light signal to the clock in mammals, circadian biologists had tantalizing clues but no answer.
The team transplanted stem cell - derived photoreceptors into another strain of mouse, called CRX null, which is congenitally blind.
I became an eye researcher completely by accident while trying to unravel the role of a protein called Ankyrin in forming biological important membrane domains in cells, in this case, the photoreceptor.
Behind the photoreceptors is another layer of cells called retinal pigment epithelium (RPE), which support the rods and cones by delivering nutrients from the bloodstream and removing waste that the rods and cones generate.
The treatment could help people who have a fault in a gene called RPE65, which causes problems in the retinal pigment epithelium (RPE), a thin layer of cells that support and nourish photoreceptors.
