Outline of Final Research Achievements

This study investigated the role of sensory prediction on postural control. Participants were exposed to predictable periodic visual perturbation in a virtual reality space. We observed that people leaned forward in response to expanding visual stimulation, suggesting that inconsistency between action and sensory information was resolved by actively changing the phase of their own motion. This was presented in two scientific conferences, ISPGR and SfN. We also investigated the role of prior knowledge on reflexive postural activities in response to the mechanical perturbation during walking. The reflex latency was shortened if participants had known when the perturbation would occur. This was published in Frontiers Human Neuroscience.
