Classical music and nice cat. Even during surgery

Portuguese veterinarians from the University of Lisbon conducted an interesting experiment . They wanted to determine whether the music to influence the state of the organism in cats undergoing surgery under anesthesia, as well, как it occurs in humans . 12 and hairy female patients who needed to undergo sterilization, in turn losing three different musical recording (classical, pop music and heavy metal).

Interestingly, the cats, like humans, were influenced by the music - although in real life they are to the music of attention does not seem to pay. Located on the operating table cats wore headphones, which were played a two-minute excerpts from three songs - «Adagio For Strings (Opus 11)," Samuel Barber, «Torn» Natalie Imbruglia and «Thunderstruck» by AC / DC. To eliminate the influence of only one volume of the music, its level in decibels strictly adhered to.

Observation of breathing and the pupils of cats have shown that AC / DC increases the level of stress of animals, and classical music, on the contrary, it decreases significantly. Miguel Carrera, professor and veterinary surgeon, пояснил, that because a lot of different music with different parameters (rhythm, harmony, the number of beats per minute), the influence of individual parameters is difficult to investigate. But the experiment proved that when the brain interprets and processes musical stimuli, following this series of chemical reactions and mechanisms cause different responses in the body.

Possibly, in the future sound stimulation patients during surgery will reduce the necessary chemical anesthesia, which, in turn, reduce the amount of side reactions that occur in response to painkillers.

In their experiments, the researchers want the future to further explore the process of brain's response to sound stimulation, using MRI, as well as to try such stimulation in other animals. Who knows, maybe there will be more calm dogs Snoop Dogg , and mice - Danger Mouse .
