A research group led by Assistant Professor Masahiro Kawasaki of the University of Tsukuba Systems and Information Systems discovered that when humans repeatedly perform tasks to reproduce auditory rhythms, beta-wave synchronization increases in the frontal region, auditory cortex, and cerebellum as learning progresses. ..
In conventional neuroscience, there have been reports of areas of the brain that are active when listening to or reproducing rhythm.However, the network between these brain regions and the brain activity correlated with rhythm learning ability were unknown.Therefore, the research group decided to identify a synchronous network between brain regions involved in rhythm motor learning, and to conduct experiments to clarify the differences that occur in this network due to the progress of rhythm learning.
A total of 6 people, 8 females and 14 males, participated in the experiment, memorized the rhythm consisting of 9 sounds presented by the earphones, and repeated the task of reproducing the rhythm by pressing a button 2 seconds later. rice field.
As a result of the experiment, the phase synchronization network in the beta wave of the frontal-auditory cortex-cerebellum was identified as the brain activity caused by rhythm motor learning, and the brain parts related to hearing, motor, and learning cooperate in rhythm learning. The need for activity became clear.
In recent years of neuroscience, it has become clear that not only one brain region but also multiple brain regions are coordinated to achieve daily functions.Now that the cerebellum, which is further known to be involved in motor learning, is synchronized with the frontal region related to memory and the auditory cortex related to sound processing, a network of multiple brain regions is important for rhythm learning. Showed the possibility for the first time.
This is expected to verify the effects of current music learning and dance learning, and to propose new learning methods by inducing brain wave synchronization.
