Just 30 minutes of musical
training can increase the blood flow in the left hemisphere of our brain which
is believed to be responsible for language processing, according to a new
study. The research by the University of Liverpool in UK suggests that the
areas responsible for music and language share common brain pathways.
Researchers from the University's Institute of Psychology, Health and Society
carried out two separate studies which looked at brain activity patterns in
musicians and non-musicians. The first study looking for patterns of brain
activity of 14 musicians and 9 non-musicians whilst they participated in music
and word generation tasks. The results showed that patterns in the musician's
brains were similar in both tasks but this was not the case for the
non-musicians. In the second study, brain activity patterns were measured in a
different group of non-musical participants who took part in a word generation
task and a music perception task. The measurements were also taken again
following half an hour's musical training. The measurements of brain activity
taken before the musical training showed no significant pattern of correlation.
However, following the training significant similarities were found. "The
areas of our brain that process music and language are thought to be shared and
previous research has suggested that musical training can lead to the increased
use of the left hemisphere of the brain," said Amy Spray, who conducted
the research as part of a School of Psychology Summer Internship Scheme.
"This study looked into the modulatory effects that musical training could
have on the use of the different sides of the brain when performing music and
language tasks. "It was fascinating to see that the similarities in blood
flow signatures could be brought about after just half an hour of simple
musical training," she said. "This suggests that the correlated brain
patterns were the result of using areas thought to be involved in language
processing," said Liverpool Psychologist, Dr Georg Mayer. "Therefore
we can assume that musical training results in a rapid change in the cognitive
mechanisms utilised for music perception and these shared mechanisms are
usually employed for language," Mayer said.
Difficulty or inability to write a coherent text message, even in people who have no problem speaking, may become a "vital" tool in diagnosing a type of crippling stroke, according to a new research. Scientists at Henry Ford Hospital focused on a 40-year-old man visiting the metro Detroit area on business who showed signs of "dystextia," a recently coined term for incoherent text messaging that can sometimes be confused with autocorrect garble. But in his case, the man saw nothing wrong with the garble. The patient had no problem with a routine bedside test of his language abilities - including fluency of speech, reading, writing, comprehension and other factors. However, when asked to type a simple text message, he not only produced garble, but he was unable to see it as such. Despite showing only slight facial asymmetry and no other symptoms, doctors determined the man had suffered an acute ischemic stroke, in which a clot or other blockage cuts off blood supply t...
