Small demonstrated this with functional-MRI scans, which reveal real-time brain activity. Half of the 24 study participants used the Internet on a daily basis, and the other half had little to no experience. (Yes, those people exist, and they're easier to find if you look for people older than 60.) First, Small compared the participants' brain activity as they read a book off a computer screen, and both groups produced similar results. But when he examined the groups as they hunted for clues about the benefits of eating chocolate and the best way to visit the Galápagos, the Web-experienced group registered twice as much activity in the frontal, temporal and cingulate areas of the brain — all of which contribute to complex reasoning.
