| Outline of Final Research Achievements |
To investigate multisensory integration in postural control of humans, we tried to verify proposed models of integration of multisensory inputs which alterations induce postural alterations. From the results of the experiments, we observed valid alterations of posture by the manipulations of the sensations physiologically. However, we found that the muscle activities are not linear summations fo each activity of sensory input and could not be explained simply by a reweighting model. As a qualitative analysis, we found out that 1) vision has large weight in postural cintrol, 2) reweighting would be caused by closing eyes, 3) reweighting would not be caused by alterations of other sensations and 4) humans would increase of body stiffness for unknown sensory inputs or discrepancy between sensory inputs.
