초록/요약
The present dissertation aimed to identify the compensatory interactions of the human somatosensory and motor systems. To do this, I observed the secondary or unintended changes in the somatosensory and motor systems after neurological damage or modulation. The observations were performed with three protocols, which are described in parts II, III, and IV. The first protocol was used to identify the secondary changes in the motor system after damage to the motor neural circuits. Part II shows that damage to part of the motor neural circuits increased the unintended motor activation within the affected side. Furthermore, the unintended motor activation occurred in the contralateral homologous area. Part III describes that an increase in the tactile or pain threshold in the somatosensory system increased the pain threshold in other body regions innervated by the same ipsilateral spinal segment. Part IV describes that anesthesia of the tactile sensory system decreased the maximum voluntary force production as well as the co-contraction between agonist and antagonist muscles. The findings can be generalized as follows. 1) The motor system compensates for deficits in voluntary motor output with synergistic co-activation of other body segments on the ipsilateral side and contralateral homologous segment. 2) The somatosensory system compensates for deficits in sensory perception with similar sensory changes in the other body segments innervated on the ipsilateral side or in adjacent spinal segments but not in those on the contralateral side. 3) The sensory system is closely linked to motor activation. Although the findings of this dissertation are incomplete, the results suggest that changes in the human body are always accompanied by compensatory changes across anatomical divisions. The phenomenon that spontaneous collective changes adapt to external environmental changes indicates that human sensorimotor systems interact with each other in a manner similar to a holonic hierarchy. I hope that the findings of my dissertation help in understanding of the human sensorimotor system through the application of an integrated and holonic approach beyond anatomical knowledge
