Frequent television viewing destroys the structure of the brain , confident Japanese scientists from Tohoku University. They conducted a study examining the structure of the frontal lobes of 276 children aged 5 to 18 years, and found that the more time they spend in front of the TV screen , the more significant changes occur in the brain responsible for intellectual development, writes The Daily Mail.

All children who participated in the experiment, watched television up to 4 hours per day, duration of one view was about two hours. After this change in brain structure were recorded using MRI – a series of images that allow to determine the size of its parts and their changes.

MRI showed that those children who spent more time in front of screen, a large amount of gray matter in the area flocked frontopolyarnoy cortex – area in front of the frontal lobes of the brain. In the normal development of the same gray matter in this region with age should become smaller: studies show that people with the highest IQ frontopolyarnaya bark exhausted.

Accumulation of gray matter in this area affects the child’s verbal intelligence – the ability to analyze it, to understand and remember the meaning of words. Those children whose frontopolyarnaya bark is large in size, have difficulty understanding the meaning of words and tend to own smaller vocabulary.

study examining the impact of television on the structure of the child’s brain had never conducted, scientists have noted, stressing that the results of the experiment should be seriously concerned about the parents of those children who are all in their free time in front of screen. However, it is worth noting that it is only on television: Does daily “hang” in front of computer similar effect on the brain is not known.

Thus scientists recognize that the relationship between the structural changes in the brain and TV definitely has, however, a frequent TV viewing is not their only reason for all the children who participated in the experiment, spent much time with his family, playing sports and read. It is possible that one of these activities could also affect the accumulation of gray matter in frontopolyarnoy crust, scientists admit.

On another negative consequence of watching TV recently told Angeline Lillard and Jennifer Peterson of the University of Virginia in Charlottesville (United Kingdom). Scientists conducted a study that involved 60 children aged four years: they were divided into two groups who answered the test questions after watching the animated series “SpongeBob” or after the lesson drawing. Comparing children’s responses, the researchers noticed that view telecast reduces cognitive abilities of the child: attention and the ability to take at least some decision – namely, choose one of the answers.

Experts attribute the findings to the fact that in the movie (as in most children’s television) all events occur very quickly: the child of tires, which means it is more difficult to concentrate, focus and resource simply exhausted. It is worth noting that scientists still managed to figure out how to influence the child’s TV show immediately after viewing, but what impact “SpongeBob” on the child’s brain in the long run, is not known.
