Fun with Brain Fitness

New research suggests that spending time searching for information on the Internet may enhance the brain power of older adult computer users -- and that it doesn't take very long to achieve positive changes. Today's issue of Experience! presents the facts of the new study and then issues a fun challenge to readers: try a simple computer-quest activity designed to illustrate the basic idea under study. You might even win a valuable brain fitness prize in the process!


Older Brains and the Internet

UCLA scientists already knew that performing online searches increased brain activation, by more than twofold, in older adults with prior computer experience when compared to those with little computer know-how. For a recap of those previous findings as reported by Experience! just click on Searching for Brain Health.

Now, new findings by the UCLA team suggest that older, minimally experienced computer users may match the brain activity levels seen in their experienced counterparts after spending only a week online.

The subjects of the study, which was described last month at a meeting of the Society for Neuroscience in Chicago, were 24 neurologically normal adults, ages 55 to 78, half of whom habitually used the Internet on a daily basis and half of whom had little computer experience. The two groups were similar in terms of age, gender, and educational background.

The researchers had the participants conduct web searches while undergoing brain scans to detect brain-circuitry responses during the activity. Following their initial scans, the participants were sent home with instructions to search the Internet one hour per day on a total of seven days over a two-week time span.

During the searches, participants used the Internet as their resource to answer questions on a variety of subjects. To succeed, they needed to identify and visit websites where they could read material pertinent to their assignments.

Afterward, a second round of brain scans was administered while participants performed the same Internet search activity, except in different topic areas. Whereas the first scans had shown significant differences in brain activation between the two groups, the second scans revealed quite similar patterns.

Initial scans of the inexperienced subjects displayed expected activity in regions of the brain involving vision, reading, language, and memory abilities. Their second scans, after a short period of home practice, showed all of that and more: activity in the middle frontal gyrus and inferior frontal gyrus. In other words, also stimulated were parts of the brain involved in working memory and decision-making skills. Researchers noted that these results tie in with the act of web searching since one's ability to hold relevant information in the working memory and to seize key facts from contending graphics and text are important during the task.

The aging human brain characteristically undergoes physical and functional changes ranging from atrophy and declines in neural activity to an increased presence of amyloid placques and tau tangles, all or any of which can affect cognition. The results of this study suggest that online training can promote desirable brain activation patterns and may bolster older adult brain functioning. The type of scan used in the study was functional magnetic resonance imaging (fMRI), a procedure that records blood-flow levels within the brain during cognitive activity. As most fMRI studies involve a small number of subjects, the planning for further research is already under way.

In summary, the UCLA researchers stated that their results suggest online searching as a possible form of brain exercise that is simple to undertake and potentially beneficial to cognitive function in older adults.

Editor's note: Related topics such as atrophy, brain cell activity, amyloid, tau, and fMRI are addressed at length in the American Senior Fitness Association (SFA) Brain Fitness for Older Adults professional education program.

The Game Is Afoot

While we're on the topic of the benefits of Internet usage, SFA has created a special way that the Internet can benefit Experience! readers. There are three questions shown below and all the answers can be found on the web. Seasoned web users should find them easily. Novice users may take a little longer but you have until November 14.

Here are the questions:

  1. According to the U.S. Census Bureau, how many Americans were age 65 and over in 2006?
  2. SFA president Janie Clark's article "Ramping Up Senior Fitness" was written for which organization?
  3. What specific SFA service earned the NCOA Health Promotion Institute's 2009 "Best Practices in Health Promotion and Wellness Award"?
