Until recently, researchers have believed that the brain only develops during the childhood and adolescent years. The thought was that once we reach adulthood, the brain ceases to develop. Contrary to this belief, we have great news: Studies from the past decade have shown that the brain can change and it does so throughout our whole life. The brain can change connections and grow new neurons, it constantly adapts to ever-changing circumstances. Which is why it’s called ‘flexible’ when we talk about ‘brain plasticity’.
