Since the start of civilization, the source of human intelligence and consciousness has been a mystery. … While much was learned about brain anatomy and function, our understanding remained very limited. In fact, through most of the twentieth century, it was believed that the brain was fixed, immutable, and static. Today, we know that the brain has great plasticity and can change, adapt, and transform. It is molded by experience, repetition, and intention. It is only because of the extraordinary technological advances over the last few decades that we can see the brain’s ability to transform on a cellular, genetic, and even molecular level. Extraordinarily, as I learned, each of us has the ability to change the very circuitry of our brain.
