Brain difference in picture teen
Your teenage daughter gets top marks in school, captains the debate team, and volunteers at a shelter for homeless people. But while driving the family car, she text-messages her best friend and rear-ends another vehicle. How can teens be so clever, accomplished, and responsible—and reckless at the same time? Jensen, a professor of neurology.

Hormones bear the brunt for much of what goes wrong in adolescence. Teenagers can seem like emotional time bombs, apt to explode at any minute into tears or rage. They engage in rebellious and risky behaviors, and it seems like they're always in trouble. But what these imaging studies show is that the brain may be behind much of this behavior. First, let's consider the prefrontal cortex, particularly how it can aid people in understanding each other. We began this article with a song called "Parents Just Don't Understand," but as it turns out, teenagers don't understand well, either.
The Teen Brain: 6 Things to Know
Low levels of marijuana use — as few as one or two times — may change the teen brain, according to a new study. The study , which looked at the brains of 46 year-old girls and boys from Ireland, England, France and Germany, found that teenagers who reported using recreational marijuana just once or twice displayed increased volume on MRI images in numerous brain regions involved in emotion-related processing, learning and forming memories. The results of the study were published Monday in the Journal of Neuroscience. The study did not say what the increased brain matter volume means, but the researchers noted that the enlargement of gray matter contradicts normal adolescent development. Another possibility is that the cannabis use has led to a growth in neurons and in the connections between them.
In matters of settled opinion, science has often found itself in the role of provocateur, even saboteur—prodding at conventional wisdoms until they yield unexpected truths, and sometimes toppling them entirely. The mysteries of celestial bodies, heredity, and mental illness have all undergone dramatic rethinking. Images from fMRI machines, for example, reveal that the brain is less like a collection of discrete, specialized modules—one for speech and one for vision, the old model—and more like an integrated network of functions that support each other. Those same images show that cerebral networks undergo dramatic, global maturation well into our 20s.
