Influence of magnetic pulses on the cortex of the human brain, you can influence his musical taste. It is found out, scientists from the Neurological Institute in Montreal and the canadian Hospital at McGill University. The results of their research published in the journal Nature of Human Behaviour.

The scientists used transcranial magnetic stimulation (TMS), which influenced the dorsolateral part of the prefrontal cortex. It is this part used for production of dopamine — the hormone responsible for feelings of pleasure associated with the «reward center» of the brain.

The researchers used three sessions with each subject or aroused parts of the cortex either suppressed or had no effect on them. After each stimulation, the subjects were asked to listen to your favorite music as well as tracks that they included the researchers.

Next, they were asked to assess the level of listening pleasure. In addition, they were given the opportunity to buy their favorite music to assess their level of interest.

It turned out that after the overwhelming stimulation, the subjects are not so much liked the track they were named the favorite. In addition, in this case, the desire to purchase a song was 40% lower than after excitatory stimulation.

Thus, scientists have shown that can interfere with CBT for the pleasure of listening to music by stimulating brain regions associated with the production of dopamine.

Robert Zatorre, Professor of neurology and neurosurgery, who heads the study notes that the influence of magnetic pulses on the cortex will be for more useful purposes.

«Many psychological disorders, such as addiction, obesity and depression, are associated with weak effects on the centers responsible for reward, he said, adding that in the future many of the problems can be solved suppressive or excitatory stimulation of these centers.
