Rewiring Your Brain
Why would you want to rewire your brain? Because the evidence suggests that doing things that cause basic changes in what you know or can do may be the most effective things you can do to increase your brain fitness.
Research evidence shows that things such as learning a new language, playing a musical instrument, and even traveling may be helpful in improving your brain’s fitness. It’s likely that these kinds of activities may be the most useful in stimulating new connections in the brain.
Dr. Michael Valenzuela at the University of New South Wales in Sydney Australia, for example, has shown that life experiences that include mentally stimulating activities may reduce risk for developing cognitive dysfunction later in life. He developed the Life Experiences Questionnaire to evaluate these kinds of experiences. Valenzuela and his colleagues showed that people with more stimulating life experiences were less likely to show atrophy of a key area in the brain, the hippocampus. It’s essential for new memories, and is one of the areas that is affected early in people who develop Alzheimer’s.
Having the kinds of experiences that can make you look at things differently, develop a different perspective, or acquire a completely new ability, may help you not just in a psychological way. More and more, we are coming to believe that stimulating mental experiences can actually change the brain in positive ways.

I saw an interesting blog post yesterday evening on the site of the Huffington Post about the potential benefits of meditation – or at least about what one woman thinks might be the benefits. Priscilla Warner writes about the contrast between Tibetan monks’ apparent calm, evident even on brain scans, and her own anxiety disorder. Ms. Warner says that she suffers from panic disorder, a severe form of anxiety in which a person can have multiple anxiety attacks every day, even in the middle of the night. Her post is titled “I Want the Brain of a Monk” Although most people don’t suffer from anxiety this severe, many people have symptoms of anxiety. And research has consistently shown that higher levels of anxiety are related to more memory problems.
What’s the relation to brain fitness? In my brain fitness class, I often mention the usefulness of meditation in helping reduce stress and anxiety, both of which have negative effects on memory. You don’t have to go to Tibet to get the benefits of meditation. If you simply take 10 minutes several times a day to break in to the ongoing rush of getting things done, you’ve made a start. Use those 10 minutes to sit quietly, relax your muscles, and breathe deeply.
If you do that every day for two weeks, I think you’ll notice that you feel calmer and better able to focus. And if you’re better able to focus, you will be better able to pay attention and remember things.
Although many people are excited about the potential for using computers to train their brains, we shouldn’t forget that other techniques have been used to the train the brain for many centuries. I’m thinking about the large number of techniques for meditation. While free computer software still requires an investment in a computer, meditation only asks you to sit or lie quietly and focus your mind.
A recently-published study shows parts of the brain in long-term meditators are larger than the same parts of the brain in people who don’t meditate. The article by Eileen Luders and her colleagues appeared in a recent issue of the journal Neuroimage (Vol. 45, No. 3, pp. 672-678, April 15, 2009). The study showed that portions of the orbitofrontal cortex and the hippocampus were larger in persons who had been regular meditators for 5 or more years. The study is interesting because the parts of the brain that were larger are often thought to be important in helping people keep themselves emotionally balanced.
A number of strategies are likely to be helpful for meditators. There has been a great deal of interest over the last several years in mindfulness meditation. Researchers have studied how it can be used in reducing anxiety and depression. Mindfulness is based on Buddhist meditation (for a brief article, click here) but you don’t have to be a Buddhist to practice meditation. In fact, one of the most important persons who has promoted mindfulness is Jon Kabat-Zinn, a researcher at the University of Massachusetts. You can see a video presentation by him on YouTube by clicking here.
