Not exact matches

The standard explanation recounts the existence of a material object, its reflection of light waves of a certain length, the transference of these light waves from the object to the perceptual organs of the observer (in this case, the eyes), the interaction of the light waves with the rods and cones of the retina, the transference of nerve impulses along the relevant nerves to the brain, and, finally, the production of the sensation of sight.

A healthy optic nerve has axons transmitting information from the eye to the brain along the nerve after considerable information processing and synaptic transmission between various cell types within the retina.

Genetic diseases like retinitis pigmentosa destroy the photosensitive cells of the eye, the photoreceptors, but often leave intact the other cells in the retina: the bipolar cells that the photoreceptors normally talk to, and the ganglion cells that are the retina's output to the brain.

Nathans is a neuroscientist who studies how cells in the retina — the light - absorbing structure at the back of the eye, which is considered part of the brain — assume their correct identities, and how those cells respond to injury and disease.

The retina sits at the back of the human eye, and contains protein cells that convert light into electrical signals that travel through the nervous system, triggering a response from the brain, ultimately building a picture of the scene being viewed.

«Light is our brain clock's primary timekeeper,» LeBourgeois says, explaining that when light hits the retina in the eye in the evening hours it suppresses the sleep - promoting hormone melatonin, delaying sleepiness and pushing back the timing of the body clock.

LCA affect the retina, the thin layer of tissue at the back of the eye that detects light as well as differentiates colors and communicates the information to the brain via the optic nerve.

The term describes the creation of a coordinated connection that allows positional information from a grid of sensors, in this case the light - sensitive cells in the retina, to be smoothly and systematically transferred to their target, the structures in the brain that interpret information from the eyes.

Rods and cones, the major light receptor cells in the mammalian eye, are densely packed across the retina where they convert light into the image - forming signals that allow the brain to create vision.
