Teenage years are already so annoying without the added burden of psychological changes. The secrets to these changes are because of the change in hormones and change and development of the body. But most parents are complaining about the changing behavior of the adults, which makes them impulsive, depressed and self centered. Psychologists and researchers blamed the unpleasant characteristics of adolescence on hormones.
However, new brain imaging scans have unconcealed a high variety of structural changes in teenagers and people in their early 20s.
Jay Giedd, at the National Institute of mental state in Bethesda, Maryland and World Health Organization followed the progress of four hundred kids, scanning them each 2 years as they grew up.
They found that adolescence brings waves of supposed 'brain pruning' throughout that kids lose concerning one per cent of their substantia grisea per annum till their early 20s.
This reduction trims unused neural connections that were overproduced within the childhood growth spurt, beginning with the a lot of basic sensory and motor areas of the brain.
These mature initial, followed by the regions concerned in language and spatial awareness then finally those concerned in additional cerebral functions.
Among the last to mature is that the terribly front of the brain's lobe, that is concerned on top of things of impulses, judgement and decision-making, that scientists say would possibly make a case for a number of the eccentric selections created by the common juvenile person.
This space conjointly controls and processes emotional data sent from the amygdaloid nucleus – the fight or flight center of gut reactions – which can account for the short-tempers among some teenagers.
As substantia grisea is lost, the brain gains substantia alba, a adipose tissue that helps conduct electrical impulses and stabilize neural connections.
Scientists say that at this stage of life the brain acts as sponge for learning, however the shortage of impulse management might result in risky behavior like drug and alcoholic abuse, smoking and unprotected sex.
Adults and the parents should understand this phenomena. This study demonstrates in adolescents, an area critically concerned in learning and habit formation is extremely aware for reward. It therefore suggests a mechanism for the way rewards would possibly form adolescent behavior otherwise, and for his or her exaggerated vulnerabilities to emotional disorders.'
But they same adolescent behavior and psychotic vulnerability is advanced and certain to involve several components of the brain therefore the DS is merely one in every of several interacting regions that area unit in all probability essential along and not in isolation.
Further analysis is required to spot extra areas that operate otherwise between the 2 age teams and to work out however such dissimilarities might have an effect on behavior and psychotic issues.
