The only truth to the old theory is that the right side of the brain controls the left side of the body and the left side of the brain controls the right. More thorough examinations, though, revealed specific disruptions in perception and cognition that illuminated how the two halves of the brain differ from each other and how they cooperate. But now we know the brain is relatively "plastic," and can generate new cells. However, the amount of alcohol required to kill brain cells would actually poison the person drinking it, so moderate drinking won't impact them.

Are you a logical, precise thinker, or would you say that you’re more free-spirited and artistic? While they look alike, the two hemispheres of the brain do function differently. There are self-help books, personality tests, therapies, and educational materials that claim to help you optimize the functions of the stronger half of your brain, get in touch with the weaker half, or even make the two halves stop their (supposedly) incessant battling inside your skull so you can finally get some peace and quiet. But it also caused some strange behavior, leading Sperry to believe that different halves of the brain controlled different activities. According to the theory of left-brain or right-brain dominance, each side of the brain controls different types of thinking.2 Additionally, people are said to prefer one type of thinking over the other. Likewise, artistic creativity isn’t just unbridled emotion. Now science has proven that there is no such thing as right and left brained people. Left brain vs. right brain People who rely more heavily on the right half of their brain tend to be more imaginative and intuitive. Recent research using brain imaging technology hasn’t found any evidence of right or left dominance.

The myth is popular, in the end, because it gives us a “scientific” way to talk about our favorite subject—ourselves. For example, young children are the best at learning new languages because their brains are still developing and they are essentially built to absorb information.

You might have even used this picture of your brain to choose a college or a career. For instance, older people tend to have a better vocabulary, and are better at differentiating between the nuances of language.

(The procedure is seldom performed today because new drugs and treatments have been developed.) Robert Louis Stevenson’s fictional characters represented the duality of human nature and explored the idea of a logical left brain (reasonable Dr. Jeky… No scientific studies have really ever been able to prove people are dominated by either side of the brain. Lateralization of brain function means that there are certain mental processes that are mainly specialized to one of the brain’s left or right hemispheres. Most of these (the Myers-Briggs personality test, for example) have about as much scientific validity as horoscopes, but they exploit a psychological phenomenon known as the Barnum Effect (or sometimes the Forer Effect): When people are offered generic descriptive statements that are presented as individualized descriptions of their own personalities, they are predisposed to accept them as meaningful and true, especially if the statements are positive. No scientific studies have really ever been able to prove people are dominated by either side of the brain. People are unique and different, but we all use our brains about the same way.
