Abstract Perceptual awareness of threshold or multi-stable stimuli varies with the pre-stimulus global state brain as indexed by EEG microstates. Similarly, also cyclic fluctuations visceral signals across cardiac and respiratory cycle. It remains to be investigated whether momentary contributes jointly independently bodily phase. We used an orientation discrimination task determine what degree subjective a visual stimulus varied microstate, phase body exerted joint independent influence on awareness. compared microstates preceding correct aware unaware trials for Our findings indicate that canonical Microstate D was more prevalent in condition, A accounted variance during inhalation exhalation. The activation D, which is anticorrelated attentional networks preceded not perceived. Inhalation instead associated A, suggesting increased arousal this However, we observed no interaction between awareness, states exert perceptual at threshold.
