The My Stroke of Insight author, a New York Times best-selling author, combines neuroanatomy with psychology to demonstrate how we can stop our emotional response and discover our way to serenity. We have been taught for fifty years that the right hemisphere of our brain controls our emotions, while the left hemisphere controls our reasoning. Now, neuroscience demonstrates that it's not quite that straightforward: in reality, our two hemispheres share an equal amount of emotional limbic tissue. As a result, there is a cognitive brain and an emotional brain in each hemisphere. Dr. Jill Bolte Taylor, author of the #1 New York Times bestseller My Stroke of Insight, describes these four unique modules of cells as the four personalities that make up each of us in this ground-breaking new book: Paragraph 1 Left Thinking; Character 2, Left Emotion; Character 3, Right Emotion; and Character 4, Right Thinking.
