Critical Gene in Retinal Development and Motion Sensing Identified

Our vision depends on exquisitely organized layers of cells within the eye's retina, each with a distinct role in perception. Johns Hopkins researchers say they have taken an important step toward understanding how those cells are organized to produce what the brain "sees." Specifically, they report identification of a gene that guides the separation of two types of motion-sensing cells, offering insight into how cellular layering develops in the retina, with possible implications for the brain's cerebral cortex.
