Abstract Over the past decade, numerous neuroimaging studies based on hemodynamic markers of brain activity have examined the feeling of body ownership using perceptual body-illusions in humans. However, the direct electrophysiological correlates of body ownership at the cortical level remain unexplored. To address this, we studied the rubber hand illusion in 5 patients (3 males and 2 females) implanted with intracranial electrodes measuring cortical surface potentials. Increased high-γ (70–200 Hz) activity, an index of neuronal firing rate, in premotor and intraparietal cortices reflected the feeling of ownership. In both areas, high-γ increases were intimately coupled with the subjective illusion onset and sustained both during and in-between touches. However, intraparietal activity was modulated by tactile stimulation to a higher degree than the premotor cortex through effective connectivity with the hand-somatosensory cortex, which suggests different functional roles. These findings constitute the first intracranial electrophysiological characterization of the rubber hand illusion and extend our understanding of the dynamic mechanisms of body ownership.

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.
