Scientists have found that searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function. According to UCLA's director of Memory and Aging Research Center Dr. Gary Small: “Our most striking finding was that Internet searching appears to engage a greater extent of neural circuitry that is not activated during reading — but only in those with prior Internet experience,”. Researchers found that during Web searching, volunteers with prior experience with internet searching registered a twofold increase in brain activation when compared with those with little internet experience.
