Practising Music Improves The Symmetry Of Your Brain

I would argue that its impossible to find someone who isnt moved by a particular anthem or piece of music. Like storytelling, inducing musicis a universal human trait, shared across all cultures for many thousands of years. It has a unique effect on the brain, inducing powerful emotional responses. A new survey in PLOS ONE confirming that music, if we make it our profession, actually rewires the circuitry of our brains.

Music, indubitably, is a very primal form of communication that activates specificcentersof our brain: those most associated with reward, planning, motivating and emotion. It is known that learning how to play a musical instrument can alter the brain: a study in 2009 demonstrated that prolonged practice increased the size of the centers of the brain responsible for hearing and dexterity. Musicians are also known for being more proficient at identifying pitching, and they are better than most at picking out speech from substantially loud background noise. Somewhat remarkably, they even have an enhanced ability to detect emotional cues in conversations.

Previous research indicates that the tissue that connects the left and right hemispheres of our brains is larger in musicians. Could it be possible that music has the power, hence, to improve the communication between the two hemispheres?

To see if musicians actually did have an improved hemispheric connectionover non-musicians, a new survey spearheaded by researchers at the University of Jyvskyl in Finland used fMRI scanners to look at the brains of two groups of people: the members of the first are always professional, practising musicians with degrees in music; the second were people who had have never professionally played a musical instrument.

Once insidein the fMRI scanners, the subjects were subjected to three very different pieces of music: classical Stravinsky, Argentinian tangoand progressive rock. The researchers were go looking for flares in neurological activity in both hemispheres of the brain; as suspected, the patterns of activity in the musicians left and right hemispheres was far more symmetrical than that of non-musicians.

The group of musicians included keyboard players, cellists, violinists, bassoonists and trombone players. Intriguingly, the most symmetrical neurologicaldisplay of such studies was observed in the brains of the keyboard players. The researchers suggest that the kinematic symmetry the symmetry of a musicians physical motions as they play their instrument of option is directly linked to the level of neurological symmetry the government had. Keyboard players have a more mirrored utilize of both hands and fingers when playing, Iballa Burunat, the lead writer of such studies, told New Scientist; hence, they are more likely to have synaptic symmetry than those playing stringed instruments.

As this study only tested the effects thatlistening to music , not actually playing it, had on the brain, these resultssuggestthat practising musicians genuinely have a rewired brain, one that communicates more effectively than most even after theyve put down their instruments.
