      abstract     = {Mind blanking (MB) is a waking state during which we do not
                      report any mental content. The phenomenology of MB
                      challenges the view of a constantly thinking mind. Here, we
                      comprehensively characterize the MB’s neurobehavioral
                      profile with the aim to delineate its role during ongoing
                      mentation. Using functional MRI experience sampling, we show
                      that the reportability of MB is less frequent, faster, and
                      with lower transitional dynamics than other mental states,
                      pointing to its role as a transient mental relay. Regarding
                      its neural underpinnings, we observed higher global signal
                      amplitude during MB reports, indicating a distinct
                      physiological state. Using the time-varying functional
                      connectome, we show that MB reports can be classified with
                      high accuracy, suggesting that MB has a unique neural
                      composition. Indeed, a pattern of global positive-phase
                      coherence shows the highest similarity to the connectivity
                      patterns associated with MB reports. We interpret this
                      pattern’s rigid signal architecture as hindering content
                      reportability due to the brain’s inability to
                      differentiate signals in an informative way. Collectively,
                      we show that MB has a unique neurobehavioral profile,
                      indicating that nonreportable mental events can happen
                      during wakefulness. Our results add to the characterization
                      of spontaneous mentation and pave the way for more
                      mechanistic investigations of MB’s phenomenology.},
