      abstract     = {Mind-blanking (MB) is the inability to report mental events
                      during unconstraint thinking. Previous work shows that MB is
                      linked to decreased levels of cortical arousal, indicating
                      dominance of cerebral mechanisms when reporting mental
                      states. What remains inconclusive is whether MB can also
                      ensue from autonomic arousal manipulations, pointing to the
                      implication of peripheral physiology to mental events. Using
                      experience-sampling, neural, and physiological measurements
                      in 26 participants, we first show that MB was reported more
                      frequently in low arousal conditions, elicited by sleep
                      deprivation. Also, there was partial evidence for a higher
                      number of MB reports in high arousal conditions, elicited by
                      intense physical exercise. Transition probabilities revealed
                      that, after sleep deprivation, mind-wandering was more
                      likely to be followed by MB and less likely to be followed
                      by more mind-wandering reports. Using classification
                      schemes, we show higher performance of a balanced random
                      forest classifier trained on both neural and physiological
                      markers in comparison to performance when solely neural or
                      physiological were used. Collectively, we show that both
                      cortical and autonomic arousal affect MB report occurrences.
                      Our results establish that MB is supported by combined
                      brain-body configurations, and, by linking mental and
                      physiological states they pave the way for novel, embodied
                      accounts of spontaneous thinking.},
