Introduction of the discussion
Voluntary movements in humans are expressed when motor commands formed in the cerebral cortex (primary motor area) drive the spinal cord motor neurons, which cause muscle contraction. Therefore, in order to elucidate the mechanism of motor expression and motor control, it is necessary to explore the relationship between neural activity at the brain and spinal level and motor output from a comprehensive perspective.
Cortical-muscle coherence analysis is attracting attention in the field of medicine and physiology as a new method to elucidate muscle activity control by the cerebral cortex during voluntary movement.
Finding the problem
Cortical-muscle coherence analysis shows how the nervous system corrects motor errors caused by unpredictable changes in the motor environment to achieve skillful motor control.
These previous studies suggest the effectiveness of body movement analysis by cortical-muscle coherence analysis regardless of whether the force is static or dynamic.
Argument
Humans move their bodies by exchanging myoelectric signals between brain and muscle via nerves extending from the brain.
“Neuroscience of physical exercise”, a science of physical exercise, not only contributes to the development of rehabilitation, but also helps athletes who want to improve their performance.
In order to deepen the system theory understanding of human body movement control, Basic physiological research such as quantitative evaluation of electroencephalogram and electromyogram is indispensable.
Conclusion
I would like to study the cause of “yips” (which is a symptom that interferes with the movement of sports due to mental causes and suddenly become unintentional playing (movement)) from a neuroscientific approach.
Examining the conclusion
By studying with Associate Professor Junichi Ushiyama, who has many achievements in analyzing body movements by cortical-muscular coherence analysis, I am sure that I could obtain various perspectives regarding my research and it would open up new horizons for me.
Therefore, I believe that Keio University’s Faculty of Environment and Information Studies is the most suitable place for pursuing my research and social contributions, and I am aspiring to enter your school and study in your laboratory.
