The ways in which particular circuits in the brain are activated determines the nature of our mental activity, ranging from perceiving sights or sounds to more abstract thought and reasoning. When neurons fire together, they grow new connections between them. Over time, the connections that result from firing lead to “rewiring” in the brain. This is incredibly exciting news. It means that we aren’t held captive for the rest of our lives by the way our brain works at this moment—we can actually rewire it so that we can be healthier and happier.
