Abstract

[Purpose] The present study aimed to assess changes in electroencephalography patterns over time in brain areas activated during a mental rotation task, by considering the relevance of the reaction time of subjects. [Subjects] The subjects were 15 healthy right-handed college students. [Methods] Forty-eight pieces of a hand picture were presented at random in one trial. Brain activity during the task was recorded using high-performance digital electroencephalography. The subjects were classified as fast, middle, and slow groups based on their reaction times. We compared the slow group with the fast group. [Results] In the fast group, brain activity was first observed in the occipital lobe, followed by the temporal lobe and the frontal lobe. In the slow group, brain activity was first observed in the occipital lobe, followed by the parietal lobe and the frontal lobe. [Conclusion] The results suggest that to appropriately activate movement-related brain regions participating in motor learning during a mental rotation task, it is important to give time rather than to demand speed, and that it is necessary for the subject to regard the image as part of his/her own body. <br>
