Now sophisticated experimental techniques suggest the brain is more like a Disney-esque animated sea creature. Every part had a specific purpose, none could be replaced or repaired, and the machine was destined to tick in unchanging rhythm until its gears corroded with age. In classical neuroscience, the adult brain was considered an immutable machine, as wonderfully precise as a clock in a locked case. The credo of this revolution is neuroplasticity - the discovery that the human brain is as malleable as a lump of wet clay not only in infancy, as scientists have long known, but well into hoary old age. But Norman Doidge’s fascinating synopsis of the current revolution in neuroscience straddles this gap: the age-old distinction between the brain and the mind is crumbling fast as the power of positive thinking finally gains scientific credibility. In bookstores, the science aisle generally lies well away from the self-help section, with hard reality on one set of shelves and wishful thinking on the other.
