Connecticut [US], March 8 (ANI): The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture. Chronically stressing the retina can weaken it and damage our ability to see. But retinal cells have a remarkable ability to wall off damage. This was discovered by a team of neuroscientists led by UConn Health.
