Where does your sense of self come from? A scientific look

Our memories and bodies give us clues about who we are, but what happens when this guidance shifts? In this mind-bending talk, science writer Anil Ananthaswamy shares how the experiences of "altered selves" -- resulting from schizophrenia, Alzheimer's, foreign limb syndrome or other conditions -- shed light on the constructed nature of identity. He breaks down where our sense of self comes from and invites us to challenge our assumptions about who we are, with the aim of building a better you and a better world.

This talk was presented at an official TED conference. TED's editors chose to feature it for you.
