Adults with little Internet experience show changes in their brain activity after just one week online, a new study finds.
The results suggest Internet training can stimulate neural activation patterns and could potentially enhance brain function and cognition in older adults.
As the brain ages, a number of structural and functional changes occur, including atrophy, or decay, reductions in cell activity and increases in complex things like deposits of amyloid plaques and tau tangles, which can impact cognitive function.
Research has shown that mental stimulation similar to the stimulation that occurs in individuals who frequently use the Internet may affect the efficiency of cognitive processing and alter the way the brain encodes new information.
