Beyond the Conscious Mind

Book excerpt: The Nobel Prize-winning work of Roger Sperry revolutionized our understanding of human consciousness by proving that separate thinking and knowledge could exist in the left and right halves of the brain. Now, popular science writer Thomas Blakeslee - author of the highly acclaimed The Right Brain - takes us to a new level of understanding based on the theory of neural Darwinism by Gerald Edelman, another Nobel Prize winner. Blakeslee explains that our neurons spontaneously organize into hundreds of groups called modules that compete to respond to every situation in our lives - from reading this paragraph to falling in love. A vast preponderance of this activity operates outside of our conscious awareness.
