Outline of Final Research Achievements

A neuroimaging model of chopsticks manipulation using fMRI was designed in order to investigate its role as a cognitive motor training in daily life. The subjects performed virtual performance of bean transfer test which is employed as one of the physical activity batteries for older adults. By introducing precise reaction and execution time, the effect of aging was significantly observed at the switching timing between the manipulations. The success rate of operation correlated with the activation in the left parietal lobe. Among the resting state networks, activation in the default mode and sensory motor networks correlated with the performance of the subjects. It was suggested that fMRI may provide the biomarker to evaluate the response to cognitive motor intervention.
