Researchers discover way to make cells in the eye sensitive to light

...sphotoreceptors are lost entirely, but the retinal ganglion cells, thecells which signal to the brain, remain intact. The researchers believethat by activating the melanopsin, these cells may gain the ability tosense and respond to light.Professor Mark Hankins, from Imperial College London and Charing CrossHo...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...sponse to light and response to light stimuli from ganglion cells, which form the circuitry to the brain. Swaroop explains that photoreceptors constitute "the first line of information capture in vision." They are part of a complex sensory system that delivers visual signals to the brain. Photoreceptors ...
