Screen Time Heavily Impacts <br />Kids' Brains, Says Study Preliminary results reveal that <br />the brains scans of adolescents <br />with more than seven hours <br />of screen time look different. The brain cortex <br />of these <br />kids showed <br />premature thinning. The brain cortex is the outermost <br />layer of the brain that processes <br />information from the physical world. Early results showed that kids <br />who have more than two hours <br />of screen time score lower <br />on thinking and language tests. The $300 million study <br />is called Adolescent Brain <br />Cognitive Development (ABCD). It's being funded <br />by the National <br />Institutes of Health (NIH). Scientists will follow <br />several thousand <br />nine to ten year olds <br />for more than a decade. Gaya Dowling, NIH study director, via 'Bloomberg'
