Although humans have no trouble localizing themselves within their own bodily borders, this sense of self-location or embodiment is a fundamental aspect of bodily self-consciousness and requires specific brain mechanisms. Recent neurological and neuroimaging evidence suggests that multisensory integration of bodily signals in two posterior brain regions in temporo-parietal and occipito-temporal cortex is crucial in coding embodiment.
In this lecture I will review three lines of research investigating brain correlates of embodiment. (1) Pathological states of embodiment (such as out-of-body experiences and autoscopic hallucinations) due to disturbed multisensory integration after focal brain damage to temporo-parietal cortex and extrastriate cortex in neurological patients. (2) Recent findings on activations of the temporo-pariatal cortex and extrastriate cortex in embodiment-related tasks using mental imagery in healthy subjects. (3) Recent experiments on the experimental induction of illusory self-location and disembodiment in healthy subjects using multisensory visuo-tactile conflict and virtual reality.
