Playing a musical instrument can
cause fundamental changes in a young person's brain, shaping both how it
functions and how it is physically structured, researchers say.
A trio of studies presented this
week at the annual meeting of the Society for Neuroscience, in San Diego,
suggested that musical training can accomplish the following:
Improve a person's ability to
effectively process information from several senses at once, Affect the way a
young person's brain develops if they begin playing music prior to age 7,
Enhance connectivity between the parts of the brain associated with creativity
All these findings ultimately could
lead to improved therapies for people with brain injuries or learning
disabilities, Dr Gottfried Schlaug, director of the Music and Neuroimaging
Laboratory at Harvard Medical School, said in a Monday afternoon news
"Music might provide an
alternative access into a broken or dysfunctional system within the
brain," said Schlaug, an associate professor of neurology at Harvard.
"Music has the unique ability to go through alternative channels and
connect different sections of the brain."
The first study, conducted by
Canadian researchers, asked trained musicians and non-musicians to respond to
sound and touch sensations at the same time.
Two sounds were delivered at the
same time a person received one touch sensation, which was intended to create
the perceptual illusion that the person actually had received two touch
Since musicians have to
simultaneously work their instrument, read sheet music and listen to the tones
they produce, the researchers predicted that they would be better able to sort
out sound from touch.
This prediction proved correct.
Non-musicians fell for the illusion, but musicians did not, researcher Julie
Roy, of the University of Montreal, said during the news conference.
"Musicians are able to ignore
the auditory stimuli and only report what they are feeling," Roy said,
adding that this is solid evidence of an improved ability to process
information from more than one sense at the same time.
The second study involved brain scans
of 48 Chinese adults aged between 19 and 21, who had at least a year of musical
training while growing up.
Researchers found that brain regions
related to hearing and self-awareness appeared to be larger in people who began
taking music lessons before age 7. Specifically, these areas tended to have a
thicker cortex, which is the outer layer of the brain.
These findings seem to indicate that
musical training can have a huge impact on the developing brain, since brain
maturation tends to peak around age 7, said lead researcher Yunxin Wang, of the
State Key Laboratory of Cognitive Neuroscience and Learning at Beijing Normal
The third study found that brain
circuitry can be reshaped by musical training.
Swedish researchers performed MRI
scans of 39 pianists who were asked to tickle the ivories on a special 12-key
piano keyboard while the scans took place.
Pianists who were more experienced
in jazz improvisation showed higher connectivity between three major regions of
the brain's frontal lobe while they improvised some music, said lead author Ana
Pinho of the Karolinska Institute, in Stockholm.
At the same time, they showed less
activity in brain regions associated with executive functions such as planning
and organizing, which could mean that trained improvisers are able to generate
music with little conscious attention or thought, Pinho said.
Because the studies were presented
at a medical meeting, the data and conclusions should be viewed as preliminary
until published in a peer-reviewed journal.
The new findings all seem to
indicate that training with a musical instrument can affect the brain in
profound ways that could prove useful both in education and in therapy,
Harvard's Schlaug said.
"Listening to and making music
is not only an auditory experience, but it is a multisensory and motor
experience," he said. "Making music over a long period of time can
change brain function and brain structure."
