In 96 healthy adults, lower gray matter volume in the insular cortex was linked to greater reported malfunction in the sense of ownership over one's body, as measured by the Embodied Sense of Self Scale. No such relationship was found for the sense of agency or narrative self. This suggests that the feeling of ownership may rely on distinct brain structures, and the scale could help screen for such neural correlates.
