"What about the 99.99+ percent of us with undivided brains? Does each of our hemispheres also perform distinct functions? Several different types of studies indicate they do. When a person performs a perceptual task, for example, brain waves, bloodflow, and glucose consumption revealed increased activity in the right hemisphere. When the person speaks or calculates, activity increases in the left hemisphere." -- Page 79
This Mercedes advertisement demonstrates the way in which the left and right brain work simultaneously to create a fully functioning human. On the left, everything is very angular, crisp, and sleek. However, the image on the left shows a lot more freedom of creativity, color, free spirit and passion. When our brains are calculative, we think more from the left side, however when faced with a task free of regulation or requirement, we think from the creative right side. The ad emulates an otherwise textbook definition of the left and right brain, creating an image of the brain segmentation that proves much more memorable and descriptive. While we have different parts of the brain for different functions, they all work together to power our daily life.
