“…Anatomically, arousal is supported by the ascending arousal system, the autonomic nervous system, and the endocrine system 18 . Early on, Lacey viewed arousal in terms of behavioral arousal (indicated by a responding organism, like restlessness and crying), cortical arousal (evidenced by desynchronized fast oscillatory activity), and autonomic arousal (indicated by changes in bodily functions) 20 .…”

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.

“… 18 , 19 Identification of this feedback utilization or decision-making ability might add to the understanding of the pathogenesis of DCD. Studies have reported that cortical arousal, personality traits, and decision-making process are highly related through a common pathway 20 ; however, their role in explaining the pathogenesis of pure DCD patients is not well explored. Moreover, there are inconsistencies in the findings as reviewed above.…”

Background: There is a gap in understanding the pathogenesis of dissociative conversion disorder (DCD), despite the disorder having a strong historical root. The role of personality and neurocognitive factors are now highlighted; however, inconsistencies are reported. This study explores the personality disposition, arousability, and decision-making ability of patients with DCD, in reference to a healthy control group (HCG). Methods: In this cross-sectional study, the sample comprised ten adult psychiatric patients with DCD. Ten participants of the HCG were matched according to age, gender, education, economic status, domicile, religious background, and handedness. The study assessed personality disposition with Temperament and Character Inventory, arousability with reaction time task, and decision-making ability with the Iowa Gambling Task (IGT PEBL version). Results: The DCD group differed significantly on personality disposition related to both temperament and character. There was also evidence of easy arousability and frustration along with deficit in executive function related to decision-making ability. Conclusion: This study highlights the presence of both temperamental and characterological factors associated with DCD. Moreover, this study identifies the role of cognitive arousability and decision-making or feedback utilization ability in the psychopathology of DCD.
