DESC: Increasingly, neurologists are beginning to discover the human brain's remarkable plasticity, its ability to grow new pathways, expand, and revive itself. At the same time, the majority of individual brain scans show severely overexcited areas and underdeveloped regions. Psychiatrist and neurological scientist doctor Daniel G. Amen describes a variety of methods, including cognitive behavior techniques, meditation, and self-hypnosis, by which people can, without the use of drugs, physically alter their own brains, and overcome negative behaviors such as obsessive thinking, anxiety, anger, and depression.
