• Thepremise of this study is that a relative decrease in intensity or lower extent of activity in a given brain area is indicative of expertise. Given that the savvygroup showed increased extent of (rather than the expected decreased) activity,Small and colleagues suggest that Internet searching can alter the brain’s respon-siveness by engaging certain brain areas to greater degrees. In other words, evenexperts, the authors claimed, can ‘‘rewire their brains,’’ reflected by the increase inspatial extent of brain activity during Internet searching compared with text read-ing.
