ever happened to you you hear a piece of music that hits you very hard?. For example, I clearly remember when I saw the film in the Mission which has music composed by Ennio Morricone. The music is beautiful, and even now every time I hear this music I feel a great emotion that I left in a great mood. I think I'm not the one that happens because the love of music is almost universal. Just look at the success of iTunes, or social status of musicians recognized. Almost all people I chat about all we can say that has one or more preferred rolas, the kind that you curl your skin. Well, a group of researchers led by Robert Zatorre, and included Valorie Salimpoor, Mitchel Benovoy, Kevin Larcher and Alain Dagher, Montreal Neurological Institute of McGill Unviersidad, Canada, investigated the effect on the brain you listen to your music.
These researchers investigated the effect of music on brain reward systems we have discussed on previous occasions. To do this they recruited 10 volunteers (5 men and 5 women) aged more than 200 applicants to participate in this study. Its main feature is that the volunteers were selected had to curl the skin every time you hear your favorite piece without getting tired of it. After selecting the subject, proceeded to take their brain imaging using positron emission tomography (PET) and magnetic resonance (fMRI). With PTSD can assess the activity of the dopaminergic system, which is a key component of reward systems, and the RMF can be located in a space-time regions that are activated. During the experiment, each volunteer will put your favorite music and favorite music on any other volunteer. In this way they could assess the difference of the dopaminergic system when they heard that special music that came up to the most intimate, versus just listening to some music that did not produce the same emotional effect.
What they found?
Well, the results were conclusive. The subjects reported more emotion in the pieces they had chosen as opposed to other parts. This correlated with an increase in heart rate response, breathing and sweating. Similarly, the functional imaging analysis showed a significant increase in dopamine release during exposure to your favorite music. Not only that, but the study found that there were areas of the brain called the caudate nucleus in which dopamine is released just before the part of the music they produced the emotional climax, and other brain regions as the nucleus accumbens in which Dopamine is released during the musical climax.
Measurement of the increase of dopamine release measured by the decrease in binding of raclopride (dopamine receptor antagonist).
This finding is formidable, since according to the authors, this is the first evidence that it produces intense pleasure listening to music is associated with the release of dopamine in the mesolimbic reward system. If we think carefully about this is doubly surprising because this system evolved to enhance basic biological behavior with a high adaptive value, such as feeding or reproduction, and as far as one might think, the music is not a basic necessity for human survival!. Another interesting aspect is that the mere anticipation of sublime musical segment that we can produce a state of emotional excitement that precedes the activation of the reward system, which has been used by great musicians to play with the height of their pieces (which reminds me of some of the symphonies of Beethoven!). This functional mechanism is not unique to music, since there are other systems that include a stage of dopaminergic release and anticipatory consummatory responses, such as the expectation of eating a delicious steak and the fact finally eating it.
And this, does that imply?
This finding helps explain the feeling so intense that experience with some pieces of music, and why the music helps us to do activities such as running for long periods of time, or environment movie scenes to achieve aesthetic almost perfect. Seeing so coldly, as one might think that great musicians are those who manage to master the art of driving slowly to our brain to release dopamine in a specific time by using sound waves. Has gee, because after reading this but I would guess, these paragraphs never be able to release one iota of dopamine by my tendency to reduce the sublime to a mere formality synaptic. Well, because the question!
