According
to recent study by UCLA psychologists provides strong evidence that a certain
region of the brain plays a critical role in memory recall. Now research that
has been published in the Journal of Cognitive Neuroscience, showed
for the first time that with the use of an electrical current stimulate that
particular region, the left
rostrolateral prefrontal cortex, which helps
to improves people's ability to retrieve memories.
We found that dramatically improved memory performance
, when we increased the excitability of this region, said Jesse Rissman, a UCLA
assistant professor of psychology, and of psychiatry and biobehavioral sciences,
the study's senior author. The left rostrolateral prefrontal cortex is responsible
for
high-level thought, which includes monitoring and integrating information
processed in other areas of the brain. This area is located behind the left
side of the forehead, between the eyebrow and the hairline which plays
important role in supporting the integration of abstract as often
self-generated, thoughts.
The technique is called transcranial direct current stimulation,
or TDCS, gives most people a warm, mild tingling sensation for the first few
minutes. This is a form of neurostimulation where very low levels of constant current are
delivered to specifically targeted areas of the brain only occasionally producing
these profound results.
