In a recent paper Perren et al. (2015) describe what they call a case of “crossed” somatophrenia. That is, a right-handed patient with a stroke in the left brain who felt that her left arm was not her own. (The attribution of “crossed” comes by analogy to aphasia: As Perren et al. emphasize in more than 90% of known cases of patients with somatoparaphrenia (Vallar and Ronchi 2009) have strokes in the right brain and say that a limb on the left side is not their own. This overwhelming difference in laterality is not dissimilar to aphasia where 90%+ of aphasiac patients have lesions in the left brain, “crossed” aphasiac patients being those (in particular right-handed individuals) who have aphasia following a lesion to the right brain.) But here we want to emphasize another detail of the case that Perren et al. mention only in passing: the patient had somatoparaphrenia for his leg, but not for his arm and the patient also had extrapersonal neglect, and mild intrapersonal neglect. This...
