Self-consciousness includes two distinct experiences: the sense of ownership of one's body and the sense of agency over one's actions. Different neurocognitive models describe their relationship. An additive model proposes that agency requires ownership; an independence hypothesis argues they rely on separate brain systems. An interactive model suggests they are interdependent, with both unique and overlapping neural correlates. A quantitative meta-analysis of neurofunctional studies identified a body-ownership-specific network (left inferior parietal lobule, left extra-striate body area), a sense-of-agency-specific network (left SMA, left posterior insula, right postcentral gyrus, right superior temporal lobe), and a shared network in the...
