In this paper, we analyze the relationship between brain activity and repeatability of actions in the process of embodied knowledge acquisition. Subjects learnt 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 process, and executed the same series of actions. We conducted same experiments twice. After the 1st 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 repeatability. In the execution task, oxy hemoglobin increase in dorsolateral prefrontal area and decrease in frontal pole with elevation of repeatability. These results suggest frontal pole relate self body imaging and dorsolateral prefrontal area relate working memory.
