American researchers have shown that playing Mozart Sonatas for two piano for at least 30 seconds is associated with a decrease in the frequency of brain activity in people with non-drug treatment of epilepsy. The article of scientists has been published in the journal Scientific Reports.
Sonatas effect for two piano in re Major (K448) on people with epilepsy has already been installed, but it was not clear how the duration of music affects and what causes it is caused. With the help of electroencephalography, scientists from the Dartmouth College measured the electrical activity of the brain of 16 adults with people with non-drug treatment of epilepsy, which have lost a set of music clips from 15 to 90 seconds, among which was K448.
It turned out that the playback of K448 for 30-90 seconds was associated with a reduction in the number of inter-view epileptiform discharges – the epilepsy of splashes of electrical activity – by 66.5 percent. Other passages did not have such an effect. Most of all the reduction has affected the left and right front cords of the brain – parts responsible for the regulation of emotional reactions. In addition, the researchers found that during listening to the endings of long duplicate sections K448, the theta rhythm of electrical activity was intensified, which is expected to be associated with positive emotions from music.
According to researchers, listening to K448 for more than 30 seconds may be associated with activation of neuron-adjustable neurons with positive emotions. It is assumed that it helps to reduce the frequency of splash of electrical activity associated with epilepsy.
