Lost of us are aware of how the brain of a child develops in the first 10 years. According to researchers, the just-born’s brain has 100 billion neurons. In the first three years, the the brain builds, and the neurons begin to connect with each other. Between 3 and 11, a dense network of connections and languages emerge, even as vision, emotions, and other motor skills develop. After 11, the brain takes a break — it begins to discard or “retire” neural pathways that are in disuse. The biological saying is that “if you don’t use it, you lose it”.
