Blind people ‘read’ letters traced on their brains with electricity

nature.com
  • New study on people who became blind during their life (ie weren’t blind from birth), and have damaged eyes / optic nerves, but not the brain part that actually “sees”.
  • The study shows that when you stimulate the “seeing” part of their brains with precise patterns of electrical impulses, they kind of see the things you’re trying to show.
  • So far scientists have only “shown” (i.e. transmitted directly into their brains) the shapes of letters like “N” or “Z”.
  • This is very early stage, but it’s a promising sign that perhaps in the future blind people will be able to see without seeing.
