Abstract and Keywords
This chapter illustrates the most recent empirical evidence of anomalies of body experiences in schizophrenia and schizotypy, with a specific focus on body ownership, sense of agency, and self-other boundary. The authors link these anomalies of body experiences to a reduced temporal sensitivity of multisensory processing, as indexed by an abnormally wide temporal binding window, which has been reported in both schizophrenia and schizotypy. Then, the authors propose specific neurobiological markers possibly associated with temporal anomalies of multisensory processing and, consequently, body experiences in schizophrenia and schizotypy. They refer specifically to the role of disorganized patterns of spontaneous brain activity, and the underlying excitation/inhibition imbalance, as a possible key to understanding anomalies of bodily-self experiences in self-disorders.
Keywords: bodily self, schizophrenia, schizotypy, body ownership, sense of agency, self-other boundary, multisensory processing, temporal binding window, excitation/inhibition imbalance, neurobiological markers
