Detailed explanation-1: -During adolescence, myelination and synaptic pruning in the prefrontal cortex increase s, improving the efficiency of information processing, and neural connections between the prefrontal cortex and other regions of the brain are strengthened. However, this growth takes time and the growth is uneven.
Detailed explanation-2: -The thoughtful, frontal lobes are not yet fully developed, so your teen may experience sudden mood swings and impulsive behavior, which can lead to accidents, fights and other dangerous activities. Your teen may be prone to anxiety and depression. Adolescents experience heightened stress-induced hormonal responses.
Detailed explanation-3: -The development and maturation of the prefrontal cortex occurs primarily during adolescence and is fully accomplished at the age of 25 years. The development of the prefrontal cortex is very important for complex behavioral performance, as this region of the brain helps accomplish executive brain functions.
Detailed explanation-4: -The brain first goes through a rapid maturation phase in the months before and after birth, and a second maturation phase throughout later childhood and adolescence. During this second phase of increased brain growth, the prefrontal cortex is the site of the brain’s most active reorganization and growth.
Detailed explanation-5: -Two brain growth spurts occur in relation to puberty. The first (13-15 years of age) increases the size and function of the brain, especially of motor areas and spatial perception activity. The second (17 years onwards) increases frontal lobe size and its connections with the rest of the brain.
