Outline of Final Research Achievements

We measured the event-related potentials, P300 and N140, using a dual-task paradigm, consisting of a somatosensory oddball task and a target-line tracking task; these parameters allowed us to quantitatively measure attention in order to investigate the relationship between sensory information processing and attentional resources.
Our results revealed that the sensorimotor information processing resources involved in human motor control regulate motor performance, and that these resources have quantitative limits. Our findings also suggested that allocation of attentional processing resources within the human brain is flexible and shifts depending on the difficulty of the task.

Academic Significance and Societal Importance of the Research Achievements

注意処理資源の配分の多寡がヒトの運動パフォーマンスにいかなる影響を与えるかという研究の解明は、今まで不明確であった運動学習や運動の習熟過程のメカニズム解明に大きく貢献すると思われる。また、神経系の習熟過程に基礎をおいた運動トレーニングや脳・脊髄運動神経系による運動制御能力の低下している高齢者などの脳の運動処方にも大きく貢献すると思われる。
