A Thousand Brains

For all of neuroscience's advances, we've made little progress on its biggest question: How do simple cells in the brain create intelligence?Jeff Hawkins and his team discovered that the brain uses maplike structures to build a model of the world-not just one model, but hundreds of thousands of models of everything we know. This discovery allows Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought.
