Increase in the cytosolic Ca2 + concentration of submucosal neurons measured by the change in the fura‐2 ratio signal evoked by butyrylcholine (1 mM) and acetylcholine (1 mM). At the end of experiment, neurons were depolarized by KCl (30 mM) in order to evoke a Ca2 + influx via voltage‐dependent Ca2 + channels. Typical tracing from 26 (out of 42 tested) cells; for statistics, see text. BCh, butyrylcholine.
