Acid did not activate esophageal nodose C fibers but inhibited their response to esophageal distension (n = 9). A: time courses of the pH values in perfused KBS and the relevant acidic KBS-induced AP in each nodose C fibers. B: averaged data of acid perfusion evoked AP in nodose C fibers. C: esophageal distension-evoked AP before and after 30-min perfusion with acid. D: time course of mechanical excitability changes (evoked by ED at 30 mmHg) in nodose C fibers after acid perfusion. E: averaged data on capsaicin-evoked AP in nodose C fibers.
