Gut markers of sense of location and disembodiment

Pressure (A), stomach pH (B) and large bowel pH (C) are associated with feelings of location, as assessed through visual analog scale (VAS) ratings (estimated marginal means). Temperature (D), stomach pH (E), and small bowel pH (F) are associated with feelings of disembodiment, as assessed through VAS ratings (estimated marginal means). Dots at the intersection of x and y coordinates emphasize estimated marginal means and their error bars at selected, representative values that span the range of observed values at regular intervals along a continuum. Error bars indicate standard errors. “All districts” indicates that the association holds true across all the three regions of the gastrointestinal tract we tested (stomach, small bowel, and large bowel). “Congruent condition” means that the association shown in dark green occurs when participants observe a congruent virtual body that matches their physical body. “Incongruent condition” means that the association shown in light green occurs when participants observe an incongruent virtual body that does not match their physical body. “All conditions” means that the association occurs both for congruent and incongruent condition. n.s. not significant; ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001.
