What part of the brain is still developing in teenagers?
In teens' brains, the connections between the emotional part of the brain and the decision-making center are still developing—and not always at the same rate. That's why when teens have overwhelming emotional input, they can't explain later what they were thinking. They weren't thinking as much as they were feeling.

Does the brain prune or lose connections?
The brain continuously builds connections based on frequent experiences. But it prunes (eliminates) connections related to infrequent experiences. In other words, you "use it or lose it" when it comes to connections made in the brain.

How does the brain work in adolescents?
Pictures of the brain in action show that adolescents' brains work differently than adults when they make decisions or solve problems. Their actions are guided more by the emotional and reactive amygdala and less by the thoughtful, logical frontal cortex. Research has also shown that exposure to drugs and alcohol during the teen years can change or delay these developments.

What happens to the brain during puberty?
Beginning at puberty, the brain is reshaped . Neurons (gray matter) and synapses (junctions between neurons) proliferate in the cerebral cortex and are then gradually pruned throughout adolescence. Eventually, more than 40% of all synapses are eliminated, largely in the frontal lobes. Meanwhile, the white insulating coat of myelin on the axons that carry signals between nerve cells continues to accumulate, gradually improving the precision and efficiency of neuronal communication — a process not completed until the early 20s. The corpus callosum, which connects the right and left hemispheres of the brain, consists mostly of this white matter.
How do addictions start?

Adolescents need to assert their independence and explore their limits, taking risks, breaking rules, and rebelling against their parents while still relying on them for support and protection.

Now scientific research is suggesting a new reason for the clashes between teenagers and their environment. Unsettled moods and unsettling behavior may be rooted in uneven brain development.

Another revealing psychological experiment is the Iowa gambling task. Subjects can choose from one of two decks of cards in the hope of picking a card that provides a reward. The "good" deck contains many cards that provide some reward; the "bad" one, many cards that provide nothing and insufficient compensation in the form of a few that hold a jackpot. The choices of adults correspond fairly well to their tested reasoning capacity. In adolescence, the correlation is much weaker.
Which part of the brain is responsible for emotional learning?
Among the last connections to be fully established are the links between the prefrontal cortex, seat of judgment and problem-solving, and the emotional centers in the limbic system, especially the amygdala.
