Research finding could help develop artificial retinas for people with vision loss
Driving a car at 40 mph, you see a child dart into the street. You hit the brakes. Disaster averted. But how did your eyes detect that movement? It's a question that has confounded scientists. Now, studying mice, researchers at Washington University School of Medicine in St. Louis have an answer: A neural circuit in the retina at the back of the eye carries signals that enable the eye to detect movement.
