“…A weakened or attenuated connection to sensory signals which maintain a stable and coherent sense of bodily self in space, at a given time, may unite the OBE and DPD, but in the case of the former, additional processes appear to mediate the experience of connection to an exocentric point in space. It is as yet unclear what these additional processes might be, but accounts of sharedbody representations being important for action and emotion, and disorders of bodyownership have been proposed within Bayesian / predictive coding frameworks (Ishida, Suzuki, & Grandi, 2015). In addition, exocentric representations / perspective-taking mechanisms are also an important part of spatial cognition and have shown associations with the occurrence of OBEs as well as having been argued to be important on theoretical grounds (Braithwaite & Dent, 2011;Braithwaite et al, 2013c, Kessler & Braithwaite, 2016 One potential puzzle is that given the OBE group scored high on measures of Depersonalization / Derealization (the CDS questionnaire), why didn't they show the same pattern as patients with DPD reported in the wider literature (i.e., a suppressed emotional response, not an enhanced one)?…”

It has been argued that disorders in body-ownership and aberrant experiences in selfconsciousness are due to biases in multisensory integration. Here we examine whether such biases are also associated with spontaneous Out-of-Body Experiences (OBEs) in a nonclinical population. One-hundred and eighty participants took part in a rubber-hand illusion (RHI) experiment with synchronous and asynchronous visual and tactile stimulation. A realistic threat was delivered to the rubber-hand after a fixed period of stimulation. Selfreport exit questionnaires measured the subjective strength of the illusion and psychophysiological measures (skin conductance responses / finger temperature) provided an objective index of fear / anxiety towards the threat. Control participants reported a stronger RHI, and revealed larger threat-related skin conductance responses during synchronous compared with asynchronous brushing. For participants predisposed to OBEs, the magnitude of the skin conductance was not influenced by brushing synchrony -fear responses were just as strong in the asynchronous condition as they were in the synchronous condition. There were also no reliable effects of finger-temperature for either group. Collectively, these findings are taken as support for the presence of particular biases in multisensory integration (perhaps via predictive coding mechanisms) in which imprecise top-down tuning occurs resulting in aberrant experiences in self-consciousness even in non-clinical hallucinators.

“…Thus, further investigation is warranted in these above mentioned regions of the brain to find any presence of the MNS. More of less the same idea of studying MNS in neural networks has also been described in some recent studies published after they year 2010 50-53. The above evidence molds the discussion toward a possibility that pathophysiology of autism in relation to neural networks will help us further explore deep insight into a collective pathophysiology of autism and mirror neurons.…”

Understanding social cognition has become a hallmark in deciphering autism spectrum disorder. Neurobiological theories are taking precedence in causation studies as researchers look to abnormalities in brain development as the cause of deficits in social behavior, cognitive processes, and language. Following their discovery in the 1990s, mirror neurons have become a dominant theory for that the mirror neuron system may play a critical role in the pathophysiology of various symptoms of autism. Over the decades, the theory has evolved from the suggestion of a broken mirror neuron system to impairments in mirror neuron circuitry. The mirror neuron system has not gained total support due to inconsistent findings; a comprehensive analysis of the growing body of research could shed light on the benefits, or the disadvantage of continuing to study mirror neurons and their connection to autism.

“…Commentators on the paper by Ward and Banissy (this issue) also suggest that mirror-touch synesthesia may be understood in terms of this predictive coding framework (see also Ishida, Suzuki, & Grandi, 2015). Ward and Banissy (this issue) focus primarily on models of this form of synesthesia that can be explained solely in terms of visually-induced hyperactivity of the somatosensory system (Threshold Theory) against a related theory in which that system is itself gated by a mechanism that distinguishes between self and other (Self-Other Theory).…”
