Internet searches may improve brain function

I've been a big fan of internet searches, Google searches in particular, since the 1990s. Web searches have changed my life- by searching the web I have learned things that have launched me on a new, very fun and satisfying career.

When I compare myself to other people, it appears I am a person who has trouble storing particular types of information, specifically proper nouns; people names and street names are particularly difficult for me. Other types of information, often completely useless, I store with great ease.

While I have a hard time storing this data, which might just be a bunch of garbage anyway, I have a great love of uncovering data and getting to the bottom of how things work.

I remember thinking the card catalog at the library was a fairly cool thing, and as kid I spent many hours looking through card catalogues by subject, learning how to use them better. It was just fun. So clearly, I was a web search fanatic waiting to happen.

When web searching started, I dove right in asking questions of the search engine as if it were some sort of genie in a bottle. Of course this is a silly way to search, which trial and error quickly revealed.

The real way to search is to think about how people will write about the problem you are trying to reasearch. Somewhere, there is a set of keywords that will get you right to the answer of your question, and those words do not include things like "the" or "and" or "is", unless you are searching for a quote or song lyrics.

This is pretty straightforward stuff, and I mention it to point out the idea that as you search, you get better at searching, and you think about the problem of searching differently as time goes by.

A study has come out that point to the idea that web searches are actually good for your brain, and good for old brains. It just gives me that warm fuzzy feeling to know that my addiction is actually good for me.

Internet use 'good for the brain'

Areas activated by reading a book in the brain of an experienced web user
For middle-aged and older people at least, using the internet helps boost brain power, research suggests.

A University of California Los Angeles team found searching the web stimulated centres in the brain that controlled decision-making and complex reasoning.

The researchers say this might even help to counteract the age-related physiological changes that cause the brain to slow down.

The study features in the American Journal of Geriatric Psychiatry.

As the brain ages, a number of changes occur, including shrinkage and reductions in cell activity, which can affect performance.

It has long been thought that activities which keep the brain active, such as crossword puzzles, may help minimise that impact - and the latest study suggests that surfing the web can be added to the list.

Lead researcher Professor Gary Small said: "The study results are encouraging, that emerging computerised technologies may have physiological effects and potential benefits for middle-aged and older adults.

"Internet searching engages complicated brain activity, which may help exercise and improve brain function."

The latest study was based on 24 volunteers aged between 55 and 76. Half were experienced internet users, the rest were not.

Each volunteer underwent a brain scan while performing web searches and book-reading tasks.

Both types of task produced evidence of significant activity in regions of the brain controlling language, reading, memory and visual abilities.

However, the web search task produced significant additional activity in separate areas of the brain which control decision-making and complex reasoning - but only in those who were experienced web users.

The researchers said that, compared to simple reading, the internet's wealth of choices required people to make decisions about what to click on in order to get the relevant information.

However, they suggested that newcomers to the web had not quite grasped the strategies needed to successfully carry out a web search.

Professor Smith said: "A simple, everyday task like searching the web appears to enhance brain circuitry in older adults, demonstrating that our brains are sensitive and can continue to learn as we grow older."

Rebecca Wood, chief executive of the Alzheimer’s Research Trust, said: "These fascinating findings add to previous research suggesting that middle-aged and older people can reduce their risk of dementia by taking part in regular mentally stimulating activities.

"Older web users - 'silver surfers' - are doing precisely this."

"Frequent social interactions, regular exercise and maintaining a balanced diet can also reduce dementia risk."

Dr Susanne Sorensen, head of research at the Alzheimer's Society, said: "Use it or lose it may well be a positive message to keep people active but there is very little real evidence that keeping the brain exercised with puzzles, games or other activities can promote cognitive health and reduce the risk of dementia."
