The discovery of neuroplasticity, the fact that thoughts can change the structure and function of our brains, even into old age, is one of the most important breakthroughs in our understanding of the brain in recent times. In The Brain That Changes Itself, Dr Norman Doidge explores the profound implications of the changing brain in a way that will permanently alter the way we look at human possibility and human nature. The documentary examines a blind man who sinks a basketball; a woman with half a brain who leads a normal life; learning disorders, strokes and brain traumas that are improved and cured; and chronic pain that is alleviated. The vast expanse of the brain's possibility is still unrealized.
