Outline of Final Research Achievements |
The passive change of the facial expression using their fingers affected the mood. Especially, opening eyes wide increased a positive mood. When measuring the brain waves, alpha waves emerged during opening eyes wide. It puzzled us since alpha waves usually appear during closing eyes and disappear during opening one’s eyes. Then we investigated the brain activity with a functional magnetic resonance imaging. The result showed that the opening eyes wide deactivated a wide area of the frontal pole cortex. This seemed to be consistent with the emergence of alpha waves: brain activities are lower at alpha waves than at beta ones. Opening eyes wide might calm down the actively working frontal pole cortex that is suggested to explore the relative value of novel alternative strategies toward more advanced goal-directed behaviors.
