| Outline of Final Research Achievements |
Cortical hemodynamic activity was recorded using near-infrared spectroscopy (NIRS) while subjects underwent the sensory organization test (SOT) protocol. Eleven healthy men underwent the SOT during NIRS recording. The statistical analyses indicated significant activation in the right frontal operculum (f-Op), right parietal operculum (p-Op), and right superior temporal gyrus (STG), right posterior parietal cortex (PPC), right dorsal and ventral premotor cortex (PMC), and the supplementary motor area (SMA) under various conditions. The activation patterns in response to specific combinations of SOT conditions suggested that (1) f-Op, p-Op, and STG are essential for sensory integration when standing balance is perturbed; (2) the SMA is involved in the execution of volitional action and establishment of new motor programs to maintain postural balance.
