The neural subjective frame. Ascending visceral information from the heart and the gut targets cortical sites, including posterior insula, ventral anterior cingulate, amygdala and somatosensory cortex. We propose that this neural representation of visceral information creates the neural subjective frame that interacts with sensory processing to create the first-person perspective inherent to subjective perceptual consciousness. The neural subjective frame would be also be necessary to other types of subjective experiences, self-consciousness and emotional feelings.
