Man with restored sight provides new insight into how vision develops

15 abril 2015

Fifteen years after California entrepreneur and downhill ski champion Mike May underwent a pioneering stem cell procedure, researchers investigate how functional his vision is. «With sight-restoration procedures becoming more developed, we’re going to see more and more cases where people are blind for long periods of time and then get their sight back,» said the study’s senior author. «But we know very little about what happens in their brains during that period. That is going to be one of the fundamental questions going forward — what happens when the lights are turned off, and what happens when you turn them back on?»
