Summary:
Scientists are one step closer to understanding how the retinas of humans and primates turn incoming light into coded messages communicated to the brain. A team of researchers funded by the National Science Foundation recently reported their discovery of a type of cell in the output (ganglion cell) layer of the retina that likely plays a key role in transforming visual images, received by the rods and cones, into coded messages headed to the brain. Ultimately, their research could help guide the design of devices to provide artificial sight to the blind.
