title: Brain activation associated with motor imagery of coordination exercises and social abilities.
abstract: The purposes of the present study were: (1) to investigate the brain activation associated with coordination exercises done by one person and those by two persons and (2) to examine the interrelationships between the brain activation and social abilities. We were interested in testing the hypothesis that viewing two-person coordination exercises evokes more sophisticated brain activation than viewing one-person coordination exercises. Thirty Japanese college students served as subjects. There were two sessions in this study: the functional magnetic resonance imaging (fMRI) session and the social ability session. In the fMRI session, the subjects were instructed to imagine they were performing coordination exercises. Also, we examined the social abilities from the viewpoint of empathising. Empathising was measured by self-reports on the Systemising, Empathy and Autism Spectrum Quotients (SQ, EQ and AQ). Regarding brain activation, blood oxygenation level dependent (BOLD) activation was significant in specific areas such as the left cuneus (Brodmann area: BA 17) when the subjects imagined they were performing exercises involving two persons, as compared with the cases when they imagined they were performing exercises involving only one person. The fMRI results showed that exercises done by two persons require more sophisticated communication than those done by one person. Furthermore, the results of this study suggested that those with more autistic traits may undergo difficulties in the exercises done by two persons, especially in the case of playing a role as a follower.
