Last night a clever magazine ad caught my eye. “Why do most 16-year-olds drive like they’re missing a part of their brain? Because they are.” It was an insurance ad and later in the text they explain the section of the brain that isn’t fully developed until people are into their 20s. It’s the dorsal lateral prefrontal cortex. “It plays a critical role in decision making, problem solving and understanding future consequences of today’s actions.” The thing I can’t figure out is why puberty comes before the development of this section of the brain.
