身体知獲得過程における動作の再現性と脳賦活反応との関係

In this paper, we analyze the relationship between brain activity and accuracy of replicating actions in the process of embodied knowledge acquisition. Subjects learned a series of actions as fundamental embodied knowledge as a experiment. Remembering and executing the actions, oxy hemoglobin increase in dorsolateral prefrontal area and decrease in frontal pole. Subjects watched a video crip of a working procedure, and executed the same series of actions as another experiment.. We conducted this experiment twice. After the First experiment, we set up three practice terms. In the observation task, oxy hemoglobin stabilize at a low level in dorsolateral prefrontal area and frontal pole with elevation of accuracy of replicating actions. In the execution task, oxy hemoglobin increase in dorsolateral prefrontal area and decrease in frontal pole with elevation of accuracy of replicating actions. These results suggest frontal pole relate self body imaging and dorsolateral prefrontal area relate working memory, and activity in these areas changes during the process of embodied knowledge acquisition.
