Since a long time scientists believe human brains stopped developing in adolescence. But now there is evidence that that's not what actually happened. The human brain does not stop developing in adolescence, but continues to grow well until the age of 20 years.
Is a researcher named Christian Beaulieu of Alberta Innovates, Health Solutions at the Department of Biomedical Engineering Faculty of Medicine & Dentistry University of Alberta, assisted by Catherine Lebel students who argue that belief.
"We want to show that there are structural changes in white matter of the brain during young adulthood. The material is white connection on the brain, connecting the various brain regions to support the ability to think. Apparently, the connection was strengthened when we are young adults," said Lebel.

In a report in the Journal of Neuroscience, Beaulieu and Lebel using magnetic resonance imaging or MRI to scan the brains of 103 healthy people aged 5 to 32 years. Each participant studied at least until the scan twice.
Results showed that young adult human brain continues to develop connections to the frontal lobe, which is a channel that is responsible for cognitive tasks that complicated.
The researchers speculate that this may be caused by frequent experiences of human life in young adulthood, such as education after high school, starting careers, independence, social relationships and develop new family.
Important observations conducted by researchers when reviewing the results of brain scans is that in some people, some brain regions has decreased the amount of white matter from time to time. It is associated with decreased brain function.
Researchers speculate that this observation needs to be further studied because it can provide new insights into the relationship between mental illness and brain structure. Because this disorder typically develops in adolescence or young adulthood.
"What's interesting is that many mental illnesses and other disorders emerge during adolescence. So we thought that maybe if a particular channel function begins to decline rapidly, it does not mean responsibility for mental disorders, but may be one factor that makes a person more prone to interference , "Beaulieu said as quoted by Medicalxpress.com, Friday (23/09/2011).
