“…Embodiment moves the seat of mental events away from the brain and reformulates cognition as resulting from brain-body interactions. An extensive literature has shown how catalogued cardiac, respiratory, gut and pupillary effects on perception 30 , action 87 , metacognition 31 and consciousness 81 , while the collective interplay of peripheral systems has discriminatory power for clinical 88 and consciousness classification 89 . We show here that within embodiment, the body is not only facilitatory, but also might impede access to our mental lives.…”

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.

“…This is consistent with the observed positive effects of exhalation on non-exteroceptive brain functions, such as associative conditioned learning 63 , 64 and the initiations of voluntary actions 65 and mental imagery of voluntary actions. 66 Alternatively, a peripheral explanation may lie in the connection between respiration and the baroreflex, known as respiratory sinus arrhythmia (RSA). 19 RSA causes faster but weaker heartbeats during inhalation compared to exhalation, 67 potentially resulting in reduced HEP amplitude during inhalation.…”

“…Data were analyzed using SPSS version 26.0. First, to test for the existence of a late CNV waveform, one-sample t -tests (two-tailed) were performed for the Active and Passive conditions to test whether the mean amplitude was significantly more negative than zero in each of these conditions ( Park et al. 2022 ).…”

Neurophysiological evidence of motor preparation in inner speech and the effect of content predictability

Self-generated overt actions are preceded by a slow negativity as measured by electroencephalogram, which has been associated with motor preparation. Recent studies have shown that this neural activity is modulated by the predictability of action outcomes. It is unclear whether inner speech is also preceded by a motor-related negativity and influenced by the same factor. In three experiments, we compared the contingent negative variation elicited in a cue paradigm in an active vs. passive condition. In Experiment 1, participants produced an inner phoneme, at which an audible phoneme whose identity was unpredictable was concurrently presented. We found that while passive listening elicited a late contingent negative variation, inner speech production generated a more negative late contingent negative variation. In Experiment 2, the same pattern of results was found when participants were instead asked to overtly vocalize the phoneme. In Experiment 3, the identity of the audible phoneme was made predictable by establishing probabilistic expectations. We observed a smaller late contingent negative variation in the inner speech condition when the identity of the audible phoneme was predictable, but not in the passive condition. These findings suggest that inner speech is associated with motor preparatory activity that may also represent the predicted action-effects of covert actions.
