Body ownership is not impaired in schizophrenia

Schizophrenia patients often experience an altered sense of self, for example, as if someone else is controlling their actions. This impairment is described as a deficit in the “sense of agency”, and while it has been well established and linked to problems with sensorimotor brain signals, another category has been left unexplored: the “sense of body ownership” by which we feel that our bodies belong to ourselves. Using a full-body illusion experiment, EPFL scientists have now determined that body ownership is not affected in schizophrenia.
