It seems that the brain of children who spend too much time ahead of screens of smart devices or video games is changing, According to a study by the National Health Organization (NIH) of the United States revealed on Sunday by the CBS network.
In 21 research centers in the United States, the NIH began to explore the brain of 4,500 children between the ages of 9 and 10 to see if the intense use of video and time games they spend on the Internet influence their development.
The first results of this study were performed with magnetic resonance imaging (MRI) show significant differences in the middle of children who use smart phones, tablets and video games more than seven hours a dayOne of the researchers, Gaya Dowling, explained in the "60 Minutes" program.
The primitive thinning images of the cortex or cerebral cortex, which processed the information sent to the brain, showed the five senses.
Thickening the card "is considered an aging process," says the scientist, stating that it was not clear if this process was harmful. "I do not know if it's due to the time consumed in front of the screens, or if it's bad," he said.
According to another scientist interviewed in the program, Kara Bagot, smartphones can have an addictive effect because the time spent in front of a screen stimulates the release of dopamine, the enjoyable hormone.
The NIH data showed that children who spent more than two hours a day on screens had had language tests and worse reasoning.
For the research, 11,000 children were examined, and they will be followed for several years to study the impact of the screens on their intellectual and social development, as well as their health.
The results will begin to be published at the beginning of 2019.
