Hanayng University announced on the 11th that Professor Kim Sung Shin of Hanyang University's Department of Cognitive Sciences discovered the neural scientific process for learning a new exercise technique. The Department of Cognitive Sciences will be newly constructed on 2021, which focuses on studies that connect the decision making process of humans and Artificial Intelligence, also creating new technologies.
Humans learn various exercise techniques from life to death. Every movement of our lives, such as walking, picking food with chopsticks, playing instruments, and driving, are done by first learning the exercise techniques. In fact, there had not been any specific discovery on what is happening in our brain as these exercise techniques are being learned.

Professor Kim's team observed the changes in the brain by providing new exercise techniques to the learner and using the fMRI (Functional Magnetic Resonance Imaging). Through the experiment, the team focused on the role of the tadpole-shaped caudate nucleus, which is related to rewarding within the brain areas. According to the observation, it has been found that as the learning proceeds, the information related to the reward for doing exercise moves from the head part to the tail part of the caudate nucleus. 
Additionaly, it has also been found that the head part of the caudate nucleus interacts with the frontal lobe of the cerebrum (Decision, assumption area), while the tail part of the caudate nucleus interacts with the motor cortex of the cerebrum (exercise technique area), and that an individual's capacity for exercise depends on the strength of the interactions. The results of this research hold meaning in discovering that the caudate nucleus, which takes part in pleasure, reward, and motive, also holds major a part in learning and habituating new exercise techniques.
Professor Kim mentioned that, "through this research, the people will deeply understand the movement disability caused by parkinsonian syndrome and also create new perspectives on providing treatment for it." He also added, "furthermore, this will become an inspiration in creating an effective AI system, as well as understanding and developing the nural-machine access system."
The reaserch, which has been supported by the Institute for Basic Science, was published on the PNAS (Proceedings of the National Academy of Sciences of the United States of America) on September 8th. Choi Ye-ra, and Shin Yoon-ha Resercher of the Institue for Basic Science Center for Neurosicence Imaging Research participated as the co-first-author of the paper, with Professor Kim Sung Shin as the corresponding author.

The image explains the information on reward moves from the head to the tail part as the learning proceeds from the beginning to the end.
The image explains that each caudate nucleus interacts with the frontal lobe and the motor cortex of the cerebrum, and that the strength of the interaction decides the exercise capacity.
