Briefly explain the changes in the brain that contribute to changes in adolescent thinking
What will be an ideal response?
Answer: The brain supplies an overabundance of gray matter during adolescence, which is later pruned at a rate of 1% to 2% per year. Increased myelination of the nerve cells makes the transmission of neural messages more efficient. The prefrontal cortex develops considerably during adolescence and allows the person to think, evaluate, make complex judgments, and monitor impulse control. Still, the prefrontal cortex does not fully develop until a person's early 20s.
