Apart from the well-known and appreciated uses of the
Internet, there might be another one, as good as or even better than all the
rest. According to a new study completed by a research team from the Semel
Institute for Neuroscience and Human Behavior at UCLA, searching the Web on a
regular basis may stimulate and even improve the brain’s functions.
The research was supervised by Professor Dr. Gary Small, and
involved 24 volunteers with ages between 55 and 76. Half of them were used to
searching the Web and the other half had no Internet experience. There were no
significant differences between their levels of education and age.
"The study results are encouraging, that emerging
computerized technologies may have physiological effects and potential benefits
for middle-aged and older adults. Internet searching engages complicated brain
activity, which may help exercise and improve brain function," Small
explained for TechNewsWorld.
The studies involved Web searches and book-reading tasks for
all the 24 volunteers, while the researchers recorded their brain circuitry
changes using functional magnetic resonance imaging (fMRI). The book-reading
tests proved that the brain activity did intensify for all volunteers the during
the activity but the ones with Internet experience presented an extended
activation of certain areas of the brain, particularly the frontal lobes,
responsible for decision making, reasoning and putting together the big
picture.
Still, as the study entered its second phase, the
researchers reached the conclusion that the brain is plastic and malleable even
beyond 50 years, as it only took the inexperienced volunteers one week of
Internet practice to reach the same brain activity as the ones using it for
many years.
"There is a lot of interest in exercising the brain --
the idea of 'use it or lose it.' There are new technologies to help us do that.
This study suggests that a simple, everyday task like searching the Internet
could be yet another way of strengthening neural circuits and creating greater
brain efficiency in the frontal lobe," said Small, who is the author of iBrain: Surviving the Technological
Alteration of the Modern Mind.
He added that there
must always be a balance in one’s activities, as the use of too much technology
can have significant negative effects. By becoming addicted to it, people can
experience attention deficit disorders and many other problems. This is why he
insists that people should divide their focus on many different activities and
balance their resources.
Dr. Small believes
that people should be informed on the enhancements that computers can bring to
the quality of life but at the same time understand the risks that come with a continuous
activity. He offered the example of today’s average young person, who spends
close to nine hours every day in front of a computer. "What's going
to be the impact of that on our survival of the fittest? That could make it
difficult for people to draw conclusions based on another's facial
expressions," Small concluded.
