The Unknown Brain

The brain can seem as mysterious as a distant galaxy, but scientists are starting to map and manipulate its many regions. In this hour, TED speakers take us on a trip through the human brain. Guests include neuroanatomist Jill Bolte-Taylor, neuroscientists Suzana Herculano-Houzel and Nancy Kanwisher, cognitive neuroscientist Rebecca Saxe, and philosopher David Chalmers.
