Brain changes in adolescence period

•Brain region that changes is called prefrontal cortex, which is right on the front of the human brain

Brain development in adolescents is linked with brain size changes, and one of the brain regions that changes is called prefrontal cortex, which is right on the front of the human brain. This area is related with decision making, planning, inhibiting inappropriate behavior, interaction with other people and self-awareness. During this period brain changes in grey matter volume for example, at the ages between 12-14 years old it reaches the highest volume later it goes down. It occurs because      the synapses between nerve cells at that age are many but then the unnecessary synapses are destroyed.

TAKING RYSKS 

Risky choices and behavior changing are characteristics in adolescence period. For instance according to the National Center for Health Statistics, there are over 13,000 adolescent deaths in the United States each year. Approximately 70% of these deaths result from motor vehicle crashes, unintentional injuries, homicide, and suicide. Emotional reactivity also increases and more time is spent with friends than with adults, it sometimes brings conflicts with adolescent’s parents.
