There are lots of changes going on in a teen’s brain during adolescence. Here are some things you should know.
The teen brain reaches its maximum physical size around age 11 for girls and 14 for boys. While it doesn’t increase in size after that, it does continue developing and maturing until the mid to late 20s. The prefrontal cortex, the region responsible for planning, prioritizing and controlling impulses, is one of the last brain regions to mature.
