Early light refines brain's circuitry for vision: Studies show importance of visual stimulation in wiring up species' brains to see

Creatures are not born hardwired to see. Instead, they depend on electrical activity in the retina to refine the complex circuits that process visual information. Two new studies in different species using different techniques show how nascent animal brains use light to wire up or construct their central vision system.
