Not only people, but mice also love good rhythm

Not only people, but mice also love good rhythm

For their research, the scientists wanted to know what was going on Synchronization beat or “win synchronization”. By this they mean the collaboration of a series of complex brain and muscle processes to recognize, respond to, and predict rhythm. The researchers wanted to find out whether the optimal musical rhythm is determined by either the brain or the body.

In their research hypotheses, they suggested that mice might prefer faster music. They are smaller animals and their bodies – including their heartbeat – run faster than humans. In contrast, called the brain’s time constant, it is the speed with which our brains can respond to something. And this constant time is the same for all kinds of animals.

For the study, 10 mice were equipped with small, wireless accelerometers. These are the sensors that can measure the dynamic vibrations of an object, in this case they were used to measure head movements. The mice were then told one-minute portions of Mozart’s “Sonata for Piano Piano (K.448) in D major.” The clips ran at four speeds: 75 percent, 100 percent, 200 percent, and 400 percent of the original speed. A group of 20 people underwent the same experiment.
