A recent study demonstrates daily surfing of the internet activates the brain of older persons. This is another example of how the environment in many forms can shape the brain and illustrates the power of neural plasticity.
24 neurologically healthy adults, aged 55 to 78, surfed the internet while their brains were being scanned by an MRI machine. Prior to the study, half the participants had used the internet daily while the other half had minimal experience. After the initial MRI scan, the participants were instructed to do internet searches for an hour a day for seven days in the next two weeks. Then they returned to the clinic for another MRI.
At baseline, those who had internet experience had much greater brain activation relative to those without internet experience. However, those who practiced on the internet during the study demonstrated significant activation in their brain to the point that they were nearly equal to the brains of the experienced internet users.
The idea of “use it or lose it” can really be taken a step further and the idea is to “use it in new ways” and novelty and complexity really is the foundation to brain health.
