      abstract     = {Embodied cognition proposes that visceral inputs play a
                      fundamental role in variations of consciousness. However,
                      the so far evidence showing that cardiac activity is
                      modulated in response to the violations of auditory
                      expectations come from pathological states of
                      unconsciousness. Here, we will investigate this question
                      during sleep by investigating cardiac responses to auditory
                      deviants in a local-global paradigm - a modified version of
                      the classic oddball. Bases on cerebral activity, this
                      dataset has revealed that transition to sleep is accompanied
                      by a preservation of low-level hierarchical predictions but
                      a breakdown of high-level hierarchical predictions,
                      confirming that this paradigm can be used to track
                      variations in conscious processing across arousal states. We
                      will here test whether cardiac responses to auditory
                      deviants follow this pattern, and additionally, might reveal
                      more subtle differences across sleep states. Preliminary
                      results suggest that cardiac responses during light NREM
                      sleep are accelerated after deviants regardless of the local
                      vs. global contrast, while cardiac responses to deviants in
                      REM sleep are accelerated in response to global, but not
                      local, deviants. Together, these results suggest that
                      cardiac responses to auditory deviants provides information
                      above and beyond cerebral markers and shed new light on the
                      potential of studying brain-heart interactions to unravel
                      differences of conscious processing across conscious
                      states.},
