TED Talks - Oliver Sacks: What hallucination reveals about our minds

Cool talk - what I have always liked about Sacks is that he never seems to lose compassion for the patients he writes about - they are not simply experiments, they are always first and foremost people. The video comes from the TED YouTube channel - you can also watch it at their site.
