The relation between prefrontal cortex and postural functions was examined in relation to developmental changes among healthy middle and upper-middle aged people were examined. The 365 participants of four age groups (40's, 50's, 60's, 70's and 80's; 226 women and 139 men) were given digit cancellation test (D-CAT) for prefrontal cortex related function assessment and the stabilometer measurements for postural functions. The results showed that developmental changes in performances for postural and prefrontal cortex related cognitive function were not parallel. Based upon these findings, characteristics of the developmental changes of cerebro-cerebellar systems in middle and upper-middle aged people were discussed.
