According to Norman Doidge, author of The Brain that Changes Itself, neuroplasticity means that the nerve cells in our brains and nervous systems are changeable, or can modify themselves. Neuroplasticity enables us to continue learning at any age, or to create new connections to take over weakened functions. We can rewire or reorganize our brains.
The actual structure and function of the brain change through the course of our lives. There is no medical treatment involved. It is a natural phenomenon that occurs within the brain. The requirement for triggering this phenomenon of neuroplasticity is exposure to an activity with intensity, frequency, and duration.
