Somatoparaphrenia (SP) is a disorder where patients deny ownership of their limb and display delusional ideas regarding it. In a review by Vallar and Ronchi (2009), they systematically reviewed the SP literature, and made several conclusions regarding the neural correlates of SP. The current review wanted to investigate whether the brain areas Vallar and Ronchi (2009) associated with SP were still supported today. This was done by systematically reviewing the literature containing lesion data on SP, and then comparing it (with the context of body ownership research) to the findings from Vallar and Ronchi (2009). The results showed extensive damage in the fronto-temporo-parietal regions (most notably the inferior parietal regions) and the underlying white matter. Considerable damage could also be seen at the subcortical level (especially in the insula and basal ganglia), together with extensive white matter damage, mostly in and around the internal capsule. Majority of the lesions were right hemisphere based. These results showed high correspondence with the findings from Vallar and Ronchi (2009). Same could be said when considering body ownership research, because the insula and the inferior parietal region are two areas that have been associated with our sense of body ownership. Although these results had some limitations, they overall contribute to a better understanding of the mechanisms behind both SP and body ownership. Future reviews on SP could try to distinguish between the mechanisms behind the delusional aspect of SP.
