Will listening to music make you smarter? Will studying to play a musical instrument make your brain grow larger 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 new times the media has been fascinated by the investigate surrounding brain improvement and music, eagerly reporting on the most recent studies to the pleasure of the music-loving parents of young children.
But all this facts - and some misinformation too - has led to generalized blurring about the role of music and music training in the improvement of the human brain. The lowest line is this: if you're confused by all you read about music study and brain development, you're nothing else but not alone.
In part, this is due to the manner in which the phrase "the Mozart Effect" has been popularized by the media and bandied about to enumerate any situation in which music has a inevitable consequent on cognition or behavior.
In fact the Mozart consequent refers specifically to a 1993 investigate looking by Frances Rauscher, Gordon Shaw and Katherine Ky and published in the prestigious journal 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 free time instructions or silence.
An enchanted media reported this absorbing investigate as "Mozart makes you smarter" - a huge over-simplification of the customary results.
As Rauscher explains in a later paper, the Mozart consequent was studied only in adults, lasted only for a few minutes and was found only for spatial temporal reasoning. Nevertheless, the looking has since launched an manufactures that includes books, Cds and websites claiming that listening to classical music can make children more intelligent.
The scientific controversy - not to mention the beloved blurring - surrounding the Mozart Effect, has given rise to a corresponding perplexity for parents. They wonder: "Should my kids even bother with music education?"
In fact the write back to this interrogate is still a resounding yes, since numerous investigate studies do prove that studying music contributes unequivocally to the inevitable improvement of the human brain. Other researchers have since replicated the customary 1993 looking that listening to Mozart improves spatial reasoning. And supplementary investigate by Rauscher and her colleagues in 1994 showed that after eight months of keyboard lessons, preschoolers demonstrated a 46% boost in their spatial thinking Iq, a skill leading for inevitable types of mathematical reasoning.
In particular, it is early music training that appears to most improve the connections in the middle of brain neurons and maybe even leads to the preparation of new pathways. But investigate shows music training has more than a casual relationship to the long-term improvement of exact parts of the brain too.
In 1994 explore magazine published an description which discussed investigate by Gottfried Schlaug, Herman Steinmetz and their colleagues at the University of Dusseldorf. The group compared 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 buildings associated with auditory processing - was bigger in the left hemisphere and smaller in the right than in the non-musicians. The musicians also had a thicker nerve-fiber tract in the middle of the hemisphere. The differences were especially striking among musicians who began training before the age of seven.
According to Shlaug, music study also promotes increase of the corpus callosum, a sort of bridge in the middle of the two hemispheres of the brain. He found that among 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 enhance motor control by speeding up transportation in the middle of the hemispheres.
Since then, a study by Dartmouth music psychologist Petr Janata published by Science in 2002, has confirmed that music prompts greater connectivity in the middle of the brains left and right hemisphere and in the middle of the areas responsible for emotion and memory, than does almost any other stimulus.
Janata led a team of scientists who reported some areas of the brain are 5% larger in expert musicians than they are in habitancy with diminutive or no musical training, and that the auditory cortex in expert musicians is 130% denser than in non-musicians. In fact, among musicians who began 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, can be up to 15% larger.
While it is now clear from investigate studies that brain region connectivity and some types of spatial thinking functionality is improved by music training, there is growing evidence that detailed and skilled motor movements are also enhanced.
Apparently the corpus callosum in musicians is critical for tasks such as finger coordination. Like a weight-lifter's biceps, this quantum of the brain enlarges to adapt 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 accomplish complicated sequences of finger movements. The non-musicians were able to make the movements as correctly as the pianists, but less performance was detected in the pianists' brains. The scientists concluded that compared to non-musicians, the brains of pianists are more productive at making skilled movements.
The study of music assuredly affects the human brain and its development, in a expected whole of ways. But what to make of all the research, especially in terms of deciding the best course of music study or appreciation for yourself or your offspring?
A 2000 description by N M Weinberger in MuSica investigate Notes makes the following perfect point: Although the Mozart consequent may not list up to the unjustified hopes of the public, it has brought unabridged interest in music investigate to the public. And listening to ten minutes of Mozart could get someone curious in listening to more unfamiliar music, chance up new vistas.
Irregardless of the hype surrounding the Mozart Effect, the unabridged schoraly evidence for music study as a tool to aid brain development, is compelling.
At the University of California School of treatment in San Francisco, Dr. Frank Wilson says his investigate shows instrumental institution enhances coordination, attention and memory and also brings about the revision of eyesight and hearing. His studies have shown that involvement in music connects and develops the motor systems of the brain, refining the entire neurological principles in ways that cannot be done by any other activity. Dr. Wilson goes so far as to say he believes music study is nothing else but 'necessary' for the total improvement of the brain.
So the lowest line is this: Music study and institution probably does aid in the improvement of the brain in discrete leading ways. And after all, if you enjoy music, there is nothing to lose by trying, and all things to gain!
