Typical in vivo contractile waves of gastric contractility at various inflation pressures. a No restraint; b when small restraint was applied, the contractile waves were significantly attenuated; c when large restraint was applied, the contractile waves were further attenuated. ACh acetylcholine administered at a concentration 10⁻⁶ mol/l. d The protocol of mechanical stimulation with stepwise inflation pressure
