A new study by MIT neuroscientists has found that memory and cognitive impairments were more associated with loss of brain “white matter,” which forms connections within and between brain regions.

“Historically a lot of people have put their eggs in the gray matter basket. This study suggests that what might really be important are the connections and the integrity of the connections,” said David Ziegler, a graduate student in the Department of Brain and Cognitive Sciences and lead author of a paper on the work that appeared in the online edition of Neurobiology of Aging in December.

Web Surfing Stimulates Aging Brains

A group of scientists found that searching the Internet doesn’t make computer-savvy, middle-aged and older adults stupid. It actually triggers key centers in the brain that control decision making and complex reasoning. In other words, we might not have to resort to word puzzles and pinochle to fend off senility.

The study, reportedly the first of its kind to assess the impact of Internet searching on brain performance, will be published in an upcoming issue of the American Journal of Geriatric Psychiatry.

“The study results are encouraging, that emerging computerized technologies may have physiological effects and potential benefits for middle-aged and older adults,” said principal investigator Dr. Gary Small, a professor at UCLA’s Semel Institute for Neuroscience and Human Behavior. “Internet searching engages complicated brain activity, which may help exercise and improve brain function.”
