Now that science has decoded DNA—parsed our cellular bits almost down to the last variation—it may seem as if biology has been completely conquered by man’s hunger for knowledge. But every time the prefix “neuro” is typed out, as it is with increasing frequency, it is clear there is one frontier left: the brain. In The New Brain, Maclean’s best writers examine the most intriguing ideas about the body’s most complex organ. Once the domain of philosophers, phrenologists, priests and psychiatrists, the brain is now being scrutinized by some of the finest scientific minds of our times. From Alzheimer’s and ADHD to autism and post-traumatic stress disorder, The New Brain is the definitive guide to some of the world’s most prominent medical mysteries.
