Neuroscientist
Sara Lazar's amazing brain scans show meditation can actually change the size
of key regions of our brain, improving our memory and making us more
empathetic, compassionate, and resilient under stress – read the article fully
and then view the video.
Led
by Dr. Lazar, a neurologist and instructor, a team of researchers at the Harvard
Medical School, have discovered that just 8 weeks of meditation can fuel
grey-matter in the hippocampus and promote brain ‘growth’. To be more specific,
the regions in the brain associated with memory, sense of self, empathy and
stress showed measurable changes sparked by meditation.
Those
who did not go take part in Dr. Lazar’s course experienced no such structural
brain changes.
16
volunteers took part in Dr. Lazar’s mindfullness course with respect to the
study, and MRI scans were taken 2 weeks
prior to and after the study.
Incredibly, it was evident that after just 8 short weeks of practicing
mindfulness meditation, Dr. Lazar’s volunteers showed thicker grey matter in
several important areas of the brain, including the left hippocampus, a small
horseshoe-shaped structure in the central brain involved in memory, learning
and emotional regulation.
Additional
parts of the brain positively affected by just eight weeks of meditation were
posterior the cingulate cortex – also important for memory and emotions; the
temporoparietal junction, involved in empathy creation; and the cerebellum,
which helps to coordinate movement.
She
said: “Although the practice of
meditation is associated with a sense of peacefulness and physical relaxation,
practitioners have long claimed that meditation also provides cognitive and
psychological benefits that persist throughout the day. This study demonstrates
that changes in brain structure may underlie some of these reported
improvements and that people are not just feeling better because they are
spending time relaxing.”
Britta
Hölzel, first author of the paper and a research fellow at MGH and Giessen
University in Germany, said: “It is
fascinating to see the brain’s plasticity and that, by practicing meditation,
we can play an active role in changing the brain and can increase our
well-being and quality of life. Other studies in different patient populations
have shown that meditation can make significant improvements in a variety of
symptoms, and we are now investigating the underlying mechanisms in the brain
that facilitate this change.”
The
meditation course seemed to cause the brain to form denser connections among
important centers that regulate our behavior and help us to be ‘smart.’
This
translates to all sorts of possible benefits – from handling stress better at
work and in our lives, to conducting out responsibilities with more élan. Sure,
you can cram for those finals, or beat your head against the wall trying to
meet a deadline at work, but maybe some life-long meditative practices can
help.
Her
talk and pictures are highly motivating for those looking for an edge in their
industry or who just need some extra oomph to get through their hectic lives.
