| Abstract | Asomatognosia and somatoparaphrenia are the non-recognition and denial of body ownership of the left limb in the setting of right hemisphere damage. A few studies pointed the relationship between its symptoms and right insula. Furthermore the empirical researches related on the mechanism of asomatognosia and neural basis are developed, since the rubber hand illusion (RHI) emerged as an experimental paradigm that allows the controlled manipulation of the experience of body ownership. A quantifiable correlate of the RHI is a shift in the perceived position of the subject's hand toward the rubber hand, so body ownership was related to activity in the right posterior insula. The addition of orbitofrontal dysfunction distinguishes somatoparaphrenia from simple asomatognosia. |
