(Why it’s time to lay the sterotypw of the teen brain to rest)
In the text, the author discusses the stereotypes about teenagers that have influenced
experts' understanding of their behavior. What are some stereotypes that you have heard
that you think don't apply to most teenagers? Why do you think these stereotypes exist
even though they don't pertain to most teenagers?

We often characterize adolescents as impulsive, reckless and emotionally unstable. We used to attribute this behavior to “raging hormones.” More recently, it’s been popular in some scientific circles to explain adolescent behavior as the result of an imbalance in the development of the brain.

According to this theory, the prefrontal cortex, the center of the brain’s cognitive-control system, matures more slowly than the limbic system, which governs desires and appetites including drives for food and sex. This creates an imbalance in the adolescent brain that leads to even more impulsive and risky behavior than seen in children – or so the theory goes.

This idea has gained currency to the point where it’s become common to refer to the “teenage brain” as the source of the injuries and other maladies that arise during adolescence.
