Anatomical model of the spinal nervous system and its application to the coordination analysis for motor learning support system

The motivation of this research is to compute internal perspective of humans through external observation. In this paper, we propose method for analyzing neural information through motion measurement. The method is on the bases of the anatomy and physiology of somatic and spinal nervous system. Muscles are classified by the innervated nerves originate from the spinal cord. The somatotopic organization inside the ventral horn of the spinal cord is utilized for topological structure of the spinal neural information. Time series of images which represent distribution of somatic information inside the spinal cord were successfully obtained through measurement and computation for sword swinging ´kesagiri´ motion. The coordination of the motion at spinal level was analyzed. The proposed method provides fundamental for motor learning support system.
