Quantification of Sensory Reweighting for the Directional Motion Perception

Abstract

The body motion is detected by the multi-sensory organs such as eyes, vestibular organ, and somatosensory system. Obtained multi-sensory cues are then integrated in the central nervous system to perceive the motion. This sensory integration process is adjusted and changed according to various sensory conditions and each sensory state. This sensory reweighting is necessary for postural control. There are, however, few quantitative models to describe the sensory reweighting for motion perception. In this study, we suggested the novel model that quantifies the visual and vestibular sensory reweighting for the motion perception.
