| Research Abstract |
Safety for walking is growing as an important issue for our daily life. The final purpose of this study is to clarify the cerebral control mechanism in walking, especially at the cessation stage of gait. Firstly, we established tasks for movement pausing by using simple movements with finger or foot. Auditoryreaction-time tasks with series of tones including unexpectedly-omitted tones were useful for exploring the brain activity for movement pausing. In the pausing processof finger and leg movements, primary hand and foot motor areas were found to be transiently active without any movement, respectively. For recording under walkingcondition, technical difficulty in avoiding artifact contaminated by body swing remained unsolved. Then we developed new tasks for exploring movement imagination process. It will be helpful in studying cerebral control mechanism for safe walking in the future.
