Is technology changing our brains? A new study adds to a growing body of research that says it is. According to the study, a 1shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may 2change the human brain as we know it. The impact of technology on our brain should not come as a 3. Professional musicians have more gray matter in brain regions 4for planning finger movements. And athletes' brains are bulkier in areas that 5hand-eye coordination. That's because the more time you devote to a specific activity, the stronger the neural(神经系统的)pathways responsible for executing that activity become. So it makes 6that people who process a constant stream of digital information would have more neurons dedicated to filtering(过滤)that information. To see how the Internet might be rewiring us, the brains of 24 adults were 7as they performed a simulated Web search, and again as they read a page of text. During the Web search, those who reported using the Internet 8in their everyday lives showed twice as much signaling in brain regions responsible for decisionmaking and complex reasoning, compared with those who had 9Internet exposure. The findings suggest that Internet use enhances the brain's 10to be stimulated, and that Internet reading activates more brain regions than printed words.
