Outline of Final Research Achievements

The sense that my body belongs to me is called body ownership. The body ownership is based on integration of multimodal information, including tactie, proprioceptive and visual information. Recently, it has been reported that patients with chronic pain have ditorted body ownership. The purpose of the present study was to investigate whether sensory incongruence leading to body disownership modulates somatosensory cortical processing using magnetoencephalography. As a result, disownership condition enhanced the activity in the primary somatosensory cortex. This suggest that the activity reflects a cortical incongruence detection mechanism involving integration of multisensory inputs.
