| Outline of Final Research Achievements |
It has been considered that changes in the neural bases for motor control/coordination and the increased importance of the mother-child attachment during development process were deeply involved in the early stage of the evolution of language ability. In this study, we investigated neural bases for bipedal locomotion and attachment-dependent social exploration by the near-infrared spectroscopy, and tried to identify the areas concerning the proficiency of these behaviors. Experimental approaches using human and macaque subjects revealed that the brain areas for bipedal control and social exploration are both in the prefrontal cortex. It has not been clarified whether the areas for these two kinds of behavior are simply located close to each other or they are functionally related sharing some parts of the neural network. Measurements with a higher resolution technique will clarify this issue in future studies.
