There has been much scientific study on the brain. A few decades ago, scientists believed that the brain was finished growing around the age of two. It was thought that after the age of two, the child’s brain was like “data entry” and the child just absorbed and continued learning, that the brain was fully developed. Through advanced medical imaging techniques, it is now known that the brain has another large growth spurt around the age of 12 and finishes up in the early to mid 20’s.
As anyone who has, or has had a child in their tweens know they get hit with a lot of changes, body, hormones, behaviors, and interests. Many of these changes have been blamed on hormones but as science has discovered most of the changes are due to the growth spurt in shiny new neurons and hard-wiring going on in your adolescents brain.
