Most brain activity begins in the first view years of life. But we did not have the ability to track brain activity as well 15 years ago. Today, neuroscientists study the brain to change brain structure and function over all ages with the use of a MRI (Magnetic Resonance Imaging) machine. An FMRI takes a video of the brain. . The FMRI helps understand the social brain.

The limbic system is used in the reward and emotion processing, which are hypersensitive in adolescents. Genes, childhood experiences, and the environment can and does shape the adolescent brain.

Gray matter volume increases during childhood and peeks in adolescents. It peeks later in boys than girls because they go through puberty at a later date. Gray matter contains cell bodies and connections between cells (the synapses). The elimination of synapses is an important process because it depends on the environment that the individual is in.

It is found that the brain continues to develop through adolescents into the ages of 20s and 30s. Adolescents is defined as the period of biological, hormonal, and physical changes of puberty and ends when an individual establishes independent role in society.

-Act on impulse-Risk takers-Get involved in fights-Get into accidents-Curious-Adventurous-Relationship quality-Sexual behavior-Peer discussions

The prefrontal cortex at the front of the brain has the ability to perform decision-making, inhibiting inappropriate behavior, social interaction, and self-awareness. Medial prefrontal cortex activity decreases in adolescents than adults when they make social decisions.

Teaching adolescents is a challenging task. In order influence the brain to pay attention, the information must have meaning and cause an emotional response. Learning is known to be a process of building neural networks in the brain. These a formed by the following ways: concrete experiences, symbolic learning, and abstract learning.

-The adolescent brain can hold up to seven items of information in working memory- Emotion can help students remember-The brain is social and requires interaction in order to develop-Practice/rehearsal is critical for learning long term-Information is retained more through visual than through other senses
