One of the most revolutionary and empowering insights coming from cutting-edge neuroscience is the fact that we can change our brains by thinking different thoughts. In her enlightening book, Train Your Mind, Change Your Brain, Sharon Begley explains that the paradigm in the scientific community for the past few centuries is that the brain is essentially fixed, hardwired, unchangeable. This view was summed up by Santiago Ramón y Cajal, a Spanish neuroanatomist, when he said, "In the adult centers the nerve paths are something fixed, ended and immutable." In other words, "the circuits of the living brain are unchanging, its structures and organizations almost as static and stationary as a deathly white cadaver floating in a vat of formaldehyde," as Begley summarized.
