Why teenagers are selfish and reckless

The majority of young children are easily agitated, only thinking about themselves, being reckless because their brains develop more slowly than their bodies.

So far psychologists have always assumed that hormonal changes cause children to behave abnormally. However, a recent study showed that teenage brains have a lot of structural changes when they turn into their twenties.

Jay Giedd, a scientist from the US National Institute of Neurological Health, studied 400 children to understand brain structure. Every two years they conduct a brain scan of a volunteer once. The team found that gray matter (nerve cells) in the brain of children decreased by 1% each year. This situation lasts until you are in your twenties.

The decline in gray matter reduces the "excess" nerve connections that are generated too much during the rapid development of teenagers. The area of ​​the brain that controls movement and sensing is where gray matter first appears. However, they enter the stage of maturity earlier than other regions, followed by the brain processing language and space

One of the last brain regions to enter into adulthood is the frontal lobe, which helps people to consider, make decisions and control impulsivity. Scientists believe that, due to the premature lobes entering adulthood, the majority of young adults often make superficial and odd decisions.

The frontal lobe also controls and processes emotional information. That helps us understand why adolescent children are easily angry.

When gray matter disappears, the brain will have more white matter - a type of fat tissue that transmits electrical impulses in the brain and stabilizes nerve connections. Neurologists say that, at an adult stage, the brain plays an important role in acquiring knowledge and living capital. But due to uncontrollable impulse, teenagers are attracted to reckless behaviors such as drinking, taking drugs, smoking, sex or driving at high speed.
