“The brain is a far more open system than we ever imagined, and nature has gone very far to help us perceive and take in the world around us. It has given us a brain that survives in a changing world by changing itself.”
― Norman Doidge,
The book The Brain that Changes Itself has not only affected the influentials of neuroscience but also has created the turning point for the laypeople to be informed about the complexity of our cognitive organ: the brain.
Until the late 19th centuries, people had believed that neuron cells were not capable of presenting any resilient activities; thus, people thought that once the brain cell has been damaged, the cell is permanently gone. The researchers struggled to understand even the basic 10% of the infrastructures/faculties of the brain, and even in that small percentage had errors.
However, as the emergence of the 21 century, scholars of the field has developed neuroscience technology to “observe” the pattern of brain activities. Well, renown Canadian psychiatrist Norman Doidge was also one of the vanguards of such. His book-The Brain That Changes Itself- is still renown as a prominent opus that amazes the readers within its context dealing with the basics of the functions, to a clear explanation of the answer to the title.
Contrary to the original belief that after childhood the brain begins a gradual process of decline, he shows us that our brains have the remarkable power to grow, change, learn, recover, and has latent effects to the human nature.
The huge leap in the study of neuroscience explained in the book occurs as Doidge explains the “brain’s plasticity”. Long before, scientists believed that each part of the brain takes charge of given function. In the 1860s, with Paul Broca’s discovery that damage to a specific part of the brain—the left frontal lobe which was associated with speech impairment— bolstered the “locational theory”. With further evidence created by other eminent scientists, such as Carl Wernicke, Gustav Fritsch, and J. L. Hitzig, brain locational theory seemed to be the only answer to the unsolvable conundrum that troubled the clique of neuroscience for ages. However, a new theory is given as a novel key to unlock the latch of the mystery.
Plasticity theory, further elaborated in the book, states that now scholars embrace the recognition that the brain is plastic and can actually change itself with exercise and understanding. Although a newbie theory compared to the former one with the paucity of empirical evidence, the theory now pervades the area, flipping every corner of the sects of neuroscience.
