Recent research has linked bodily self-consciousness to the processing and integration of multisensory bodily signals in temporoparietal, premotor, posterior parietal and extrastriate cortices. Studies in which subjects receive ambiguous multisensory information about the location and appearance of their own body have shown that these brain areas reflect the conscious experience of identifying with the body (self-identification (also known as body-ownership)), the experience of where 'I' am in… 
Bodily self-consciousness and its disorders.
Coupling Inner and Outer Body for Self-Consciousness
Visual consciousness and bodily self-consciousness.
TLDR
Several lines of evidence suggest reciprocal relationships between vision and bodily signals, indicating that a comprehensive understanding of visual and bodily self-consciousness requires studying them in unison.
Distinct illusory own-body perceptions caused by damage to posterior insula and extrastriate cortex.
TLDR
Qualitative lesion analysis in the-to date-largest group of patients with autoscopic hallucination and heautoscopy is performed and compared the location of brain damage with those of control patients suffering from complex visual hallucinations, suggesting abnormal bodily self-consciousness during heautoscope is caused by a breakdown of self-other discrimination regarding affective somatosensory experience.
Underlying mechanisms of episodic autobiographical memory and self-consciousness
Cognitive neuroscience has been examining consciousness associated with the subject, that is the self of the conscious experience and its related multisensory processing of bodily signals, the
Vestibular contribution to bodily self-consciousness and multisensory cortical processing
TLDR
It is suggested that the vestibular system contributes to 1PP and multisensory cortical processing and should not be neglected when studying higher brain function and neurobiological mechanisms of consciousness.
Unconscious integration of multisensory bodily inputs in the peripersonal space shapes bodily self-consciousness
TLDR
The results indicate that multisensory inputs, even outside of awareness, are integrated and affect the phenomenological content of self-consciousness, grounding BSC firmly in the field of psychophysical consciousness studies.

Video Ergo Sum: Manipulating Bodily Self-Consciousness
TLDR
An experiment that uses conflicting visual-somatosensory input in virtual reality to disrupt the spatial unity between the self and the body found that during multisensory conflict, participants felt as if a virtual body seen in front of them was their own body and mislocalized themselves toward the virtual body.

Neural Basis of Embodiment: Distinct Contributions of Temporoparietal Junction and Extrastriate Body Area
TLDR
Evoked potential mapping and a distributed linear inverse solution show that distributed brain activity at the EBA and TPJ as well as their timing are crucial for the coding of the self as embodied and as spatially situated within the human body.
Neuropsychology: Stimulating illusory own-body perceptions
TLDR
Stimulation at this site elicited illusory transformations of the patient's arm and legs and whole-body displacements, indicating that out-of-body experiences may reflect a failure by the brain to integrate complex somatosensory and vestibular information.
