The neural monitoring of visceral inputs might play a role in first-person perspective
In healthy participants, how the brain responds to heartbeats, measured as the heartbeat-evoked response (HER), correlates with perceptual, bodily, and self-consciousness.

Cardiac sympathetic-vagal activity initiates a functional brain-body response to emotional arousal
Proceedings of the National Academy of Sciences.

Estimated communication from parasympathetic (vagal) to EEG distinguishes low vs high arousal.
Ascending parasympathetic modulations to delta, theta and gamma correlated to the subjective report of arousal.
Ascending parasympathetic inputs shape the perceived arousal in emotion elicitation
Ascending cardiac inputs may shape the feeling of stress

Dynamic fluctuations in ascending heart–to–brain modulations under mental stress elicitation

Stress elicitation induced an increased variability in the directional heart–to–brain functional interplay
Primarily from sympathetic activity targeting a wide range of EEG oscillations.
Bodily feedback may modulate the perceived stress caused by an increased cognitive demand.
