Neurons and their axons are called the gray matter, which decreases during adolescence.
Myelin, also called white matter, insulates the neurons and their axons, and builds stronger and faster connections between brain centers
Para ventricular central brain selectively stimulated by pubertal hormones
The brain plasticity - the human creativity – booms during adolescence and fades away after the age of 25 yrs.
Gray matter helps adolescent’s cognitive functions better and allows for specific skills and age-related decrement starting from age 12 years
Myelin insulation of axons in prefrontal areas is the last to be completed and is not finished until age 25 years
Adolescent brain reward-seeking regions of the brain develop before the regions responsible for planning and emotional control
The stimulation of Para ventricular areas (dopamine mediated) typically begin around age 10 to 12 years and increases over the next several years.
But the prefrontal cortex which keeps a lid on impulsive actions doesn’t approach full development until a decade later leaving an imbalance during the interim years.
Puberty is starting too early, boosting hormones when the prefrontal cortex even less mature
