Morphine, which inhibits release of acetylcholine from neurons in the myenteric plexus, also inhibits the spontaneous electrical activity of some myenteric neurons. To determine whether morphine acts at a site presynaptic to these neurons, we investigated this morphine effect under conditions of synaptic transmission blockade.
