Acetylcholine accelerates slow wave activity in guine-pig gastric pylorus.

A. The two traces were recorded from two electrodes placed 4.5 mm apart. Upon addition of acetylcholine (ACh) (100 nM), there was a reversible acceleration of slow wave activity. B. Under resting conditions there was little synchrony (regions 1 and 3), but this increased markedly when the frequency was accelerated by ACh (region 2). Reproduced from van Helden and Imtiaz (2003).
