This is just a study, and I'm definitely not taking any conclusions from this â I'm mostly keeping this to later group with more information if any arises.
The researchers recruited twenty-four volunteersâa dozen experienced Web surfers and a dozen novicesâand scanned their brains as they performed searches on Google. (Since a computer wonât fit inside a magnetic resonance imager, the subjects were equipped with goggles onto which were projected images of Web pages, along with a small handheld touchpad to navigate the pages.) The scans revealed that the brain activity of the experienced Googlers was much broader than that of the novices. In particular, âthe computer-savvy subjects used a specific network in the left front part of the brain, known as the dorsolateral prefrontal cortex, [while] the Internet-naĂŻve subjects showed minimal, if any, activity in this area.â As a control for the test, the researchers also had the subjects read straight text in a simulation of book reading; in this case, scans revealed no significant difference in brain activity between the two groups. Clearly, the experienced Net usersâ distinctive neural pathways had developed through their Internet use. The most remarkable part of the experiment came when the tests were repeated six days later. In the interim, the researchers had the novices spend an hour a day online, searching the Net. The new scans revealed that the area in their prefrontal cortex that had been largely dormant now showed extensive activityâjust like the activity in the brains of the veteran surfers. âAfter just five days of practice, the exact same neural circuitry in the front part of the brain became active in the Internet-naĂŻve subjects,â reports Small. âFive hours on the Internet, and the naĂŻve subjects had already rewired their brains.â He goes on to ask, âIf our brains are so sensitive to just an hour a day of computer exposure, what happens when we spend more time [online]?â
