Oliver Sacks has a new book out called The Mind's Eye where he explores how our eyes and brain interact to form the world we see. He accounts some amazing case studies of people who have become blind, or recovered from a sort of blindness, and how their brains adjust to the new environment.
In this video, he talks about something called Face Blindness, or Prosopagnosia, which he himself suffers from.
