Will listening to music make you smarter? Will learning to play a musical instrument make your brain grow more spectacular than normal? Questions like these ones have been popping up all over the place in the past few years, and not just in scientific journals either. In recent times the media has been mesmerized by the exploration surrounding brain development and music, eagerly reporting on the latest studies to the delight of the music-loving parents of young children. But all this selective information – and a heap of misinformation too – has led to generalized confusedness when it comes to the role of music and music training in the development of the humane brain. The bottom line is this: if you’re confused by all you read when it comes to music study and brain development, you’re surely not alone. In part, this is due to the manner in which the phrase “the Mozart Effect” has been extrapolated by the media and bandied when it comes to to describe any circumstance in which music has a positive effect on psychological result of perception learning and reasoning or behavior. In fact the Mozart Effect refers quintessentially to a 1993 exploration finding by Frances Rauscher, Gordon Shaw and Katherine Ky and published in the esteemed diary Nature. The scientists found that 36 college students who listened to 10 minutes of a Mozart sonata performed higher on a subsequent spatial-temporal task than after they listened to relaxation instructions or silence. An enchanted media reported this interesting exploration as “Mozart makes you smarter” – a big over-simplification of the basi results. As Rauscher explains in a later paper, the Mozart Effect was studied only in adults, lasted only for a few minutes and was found only for spatial temporal reasoning. Nevertheless, the finding has since launched an industry that includes books, CDs and web sites claiming that listening to classical music may make children more intelligent. The scientific controversy – not to mention the general confusedness – surrounding the Mozart Effect, has given rise to a matching perplexity for parents. They wonder: “Should my kids even bother with music education?” In fact the answer to this question is still a resounding yes, since a great deal of exploration studies do prove that studying music contributes unequivocally to the positive development of the humane brain. Other researchers have since replicated the original 1993 finding that listening to Mozart improves spatial reasoning. And further exploration by Rauscher and her colleagues in 1994 showed that after eight months of keyboard lessons, preschoolers demonstrated a 46% boost in their spatial reasoning IQ, a skill necessary for sure types of mathematical reasoning. In particular, it is early music training that appears to most beef up the connections amid brain neurons and perhaps even leads to the establishment of new pathways. But exploration shows music training has more than a casual kinship to the long-term development of specific parts of the brain too. In 1994 Discover magazine published an article which discussed exploration by Gottfried Schlaug, Herman Steinmetz and their colleagues at the University of Dusseldorf. The group equated magnetic resonance images (MRI) of the brains of 27 classically trained right-handed male piano or string players, with those of 27 right-handed male non-musicians. Intriguingly, they found that in the musicians’ planum temporale – a brain structure related with auditory processing – was more spectacular in the left hemisphere and littler in the right than in the non-musicians. The musicians also had a thicker nerve-fiber tract amidst the hemisphere. The deviations were peculiarly striking amongst musicians who started out training before the age of seven. According to Shlaug, music study likewise promotes growth of the corpus callosum, a sort of bridge amid the two hemispheres of the brain. He found that amid musicians who started their training before the age of seven, the corpus callosum is 10-15% thicker than in non-musicians. At the time, Schlaug and other researchers speculated that a larger corpus callosum might improve motor control by speeding up communication amidst the hemispheres. Since then, a study by Dartmouth music psychologist Petr Janata published by Science in 2002, has confirmed that music prompts more outstanding connectivity amidst the brains left and right hemisphere and among the areas responsible for emotion and memory, than does almost any other stimulus. Janata led a team of scientists who reported a good deal of areas of the brain are 5% more spectacular in expert musicians than they are in people with little or no musical training, and that the auditory cortex in professional musicians is 130% denser than in non-musicians. In fact, amongst musicians who started out their musical studies in early childhood, the corpus callosum, a four-inch bundle of nerve fibers connecting the left and right sides of the brain, may be up to 15% larger. While it is now clear from exploration studies that brain region connectivity and numerous types of spatial reasoning functionality is bettered by music training, there is growing proof that elaborate and skilled motor movements are also enhanced. Apparently the corpus callosum in musicians is necessary for tasks such as finger coordination. Like a weight-lifter’s biceps, this share of the brain enlarges to accommodate the increased labour assigned to it. In a study conducted by Dr. Timo Krings and reported in Neuroscience Letters in 2000, pianists and non-musicians of the same age and sex were required to carry out complex sequences of finger movements. The non-musicians were competent to make the movements as correctly as the pianists, but less action was detected in the pianists’ brains. The scientists concluded that equated to non-musicians, the brains of pianists are more effective at making skilled movements. The study of music unquestionably affects the humane brain and it is development, in a staggering number of ways. But what to make of all the research, specially in terms of resolving the best course of music study or appreciation for yourself or your offspring? A 2000 article by N M Weinberger in MuSICA Research Notes makes the following magnificent point: Although the Mozart Effect may not list up to the unjustified hopes of the public, it has brought widespread interest in music exploration to the public. And listening to ten minutes of Mozart could get an individual mesmerized in listening to more unfamiliar music, opening up new vistas. Irregardless of the hype surrounding the Mozart Effect, the overall academic proof for music study as a tool to help brain development, is compelling. At the University of California School of Medicine in San Francisco, Dr. Frank Wilson says his exploration shows instrumental exercise enhances coordination, concentration and memory and also brings when it comes to the betterment of eyesight and hearing. His studies have shown that involvement in music connects and formulates the motor systems of the brain, refining the entire neurological scheme in ways that can not be done by any other activity. Dr. Wilson goes so far as to say he believes music instruction is in truth ‘necessary’ for the total development of the brain. So the bottom line is this: Music study and exercise in all likelihood does support in the development of the brain in respective essential ways. And after all, if you receive pleasure from music, there is not one thing to lose by trying, and everything to gain!
