Doing Internet Searches Boosts Older Brains 65

Hugh Pickens writes "Medical News Daily reports that researchers have found signs of enhanced neural stimulation in parts of the brain that control decision-making and reasoning when they scanned the brains of middle-aged and older first-time Internet users after only seven days of performing Internet searches. 'We found that for older people with minimal experience, performing Internet searches for even a relatively short period of time can change brain activity patterns and enhance function,' says Dr Gary Small, a professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA. At the start of the study, the participants performed Internet searches while the researchers took fMRI scans of their brains to track changes in blood flow in the brain and record subtle changes in neural activity. After practicing searching the Internet for 7 days over 2 weeks at home, the brains of the Internet novices showed activity in the same regions as before, but this time there was new activity in the middle frontal gyrus and inferior frontal gyrus, the parts of the brain that are important for working memory and decision-making. 'You can exercise your mind by using the Internet, but it depends on how it's used,' adds Small. 'If you get hooked on gambling or eBay shopping, that may not be positive.'"

        On the contrary, I'd pay good money for 50 Cent and Kanye West to travel to Mars, so long as the trip was guaranteed one-way.

        • Mars Immigration Department called and said they would take 50. But they will not grant Kanye a travel visa under any circumstances. Probably because the Intergalactic Awards Show is coming up soon and will be hosted there.

      I was thinking along similar lines, but I'm more inclined to attribute it to the fact that they're first-time Internet users, and that learning how to use a search engine and formulate a good search for the first time is bound to show brain development and "enhanced neural stimulation". Replace "Internet searching" with anything else and introduce it to people who have never done it before and I bet you'll find new brain development and enhanced neural stimulation. It's called "learning" and, shockingly, when people learn new things their brain structure changes.
      • Exactly. "Learning new skills stimulates brain -- film at 11" would be a better headline.

          Still, some new skills stimulate the brain more than others. I was surprised to find that learning a new keymap stimulated my brain the same amount as immersing myself in a foreign language for a few hours.

When you search threw the stuff you find a lot of stuff that you have never though about based on that topic... For example I just did a google search for well. Thinking of a Well for water where Little Timmy can fall in. Then the first search result was for Wells Fargo then there are a bunch of site for wellness and there is a result for digging a well. So for that search result I was exposed 3 different idea at once

      • Yeah I used to get the same thing until I learned about lmgtfy.com (letmegooglethatforyou.com). You type in the search phrase and and hit the "Google Search" button. It gives you a link that has animation of someone typing in the search term and moving the mouse to click search. It then displays normal google results. Its pretty effective in making the person feel like they could have done it for themselves. (example link: http://lmgtfy.com/?q=slashdot [lmgtfy.com] ) Enjoy!

  • Performing any new activity creates stress, because the brain wants to follow its existing neural pathways to accomplish a set of behavior. This is where the phrase "you can't teach an old dog a new trick" expression comes from. After a short time of performing the repetitive behavior, as a way to overcome the stress, the brain will start to create new neural pathways which strengthen with additional repetition. This behavior is not unique to internet searches and it surprises me that it is news-worthy.
  • If some computer-related activities can (apparently) change the way the brain works, I wonder if too much of it can have adverse effects. For example I've been using computers for about 30 years now and it's pretty apparent that my brain works quite differently than people who don't. Has this left me at a disadvantage WRT social interaction? I wonder if anyone has done research on that. *searches Google for it* d'oh!

    ... their brain works more.

    That's all there is to it. Age, searching, internet, none of that is relevant other than being conditions under which it can happen. Identical results can be had with kids doing stem completion tasks (E A _ _ _ = E A R T H), college students doing a Stroop task (words naming colors, in that color or a different one), and any brain you can get to sit still and problem solve while stuck inside a tube with horrible noises going on.

    TFA is a prime example of someone doing a far too specific test on a general principle and either thinking or pretending to have discovered something. I'm going to go with "pretending" since the new results after practice were seen in the middle and interior frontal gyri, and he claims these results are due to two specific processing tasks, but neglects to mention that the two regions make up more than half the frontal lobes in which there are obviously a great number of things going on, many of which would be occurring during the task, their design is completely incapable of telling the difference between excitatory and inhibitory activation, and there is no word on whether the 'enhanced' neural activity correlated with improved ability to search and/or answer relevant questions, without which one could just as easily make a case that the increased activation was a sign of boredom for having to do the same damn stuff again that they've been doing the past two weeks at home.

    Someone needs to do a study and see whether asking hard questions about this stuff of researchers giving talks on it when they clearly don't know enough about what they're doing makes their brains light up in the right places, because if you make people think, their brain works harder. Wouldn't have happened here, because they wouldn't have been forced to answer the questions -- this was just a poster. Anyone can get any poster into one of these conferences as long as it says fMRI on it.

It actually does help them as unlike simply learning something new, the internet and computer skills quickly leads onto a range of other skills that they can pick up quickly by themselves.
