WEDNESDAY, Feb. 2 (HealthDay News) -- Electrical stimulation of
the brain can bring a flash of insight that can help people solve
new, difficult problems, research suggests.
Investigators in Australia found that volunteers who received
electrical stimulation of the brain's anterior temporal lobes were
three times more likely to be able to figure out a challenging,
unfamiliar problem than participants in a control group.
Many people have difficulty achieving creative leaps needed to
solve new problems because they tend to stick to strategies and
insights that have been successful before, study authors Richard
Chi and Allan Snyder, from the Center for the Mind at the
University of Sydney, explained in a news release from the Public
Library of Science.
The use of "transcranial direct current stimulation" temporarily
increases or decreases the activity of populations of brain cells,
the study authors said. This safe, noninvasive technique can be
used to manipulate the competition between the left and right
hemispheres of the brain by inhibiting and/or activating certain
networks, they explained.
According to Chi and Snyder, the right anterior temporal lobe is
associated with insight or finding new meaning, and the inhibition
of activity in the left anterior temporal lobe can lead to thinking
that is less likely to be influenced by preconceptions. However,
the authors noted that more research is needed.
The study is published online Feb. 2 in the journal
Whole Brain Atlas explains more about the anatomy
of the brain.
