A slow-wave potential is a rhythmic electrophysiological event in the gastrointestinal tract. The normal conduction of slow waves is one of the key regulators of gastrointestinal motility. Slow waves are generated and propagated by a class of pacemaker cells called the interstitial cells of Cajal, which also act … Visa mer In the human enteric nervous system, the slow-wave threshold is the slow-wave potential which must be reached before a slow wave can be propagated in gut wall smooth muscle. Slow waves themselves seldom cause any … Visa mer Gastric slow waves occur at around 3 cycles-per-minute in humans and exhibit significance variances in both amplitudes and propagation velocities in the stomach due to the existence … Visa mer WebbIn the jejunum, distension prevents a previously unknown tetrodotoxin‐resistant neuronal response to luminal nutrient stimulation, and demonstrates that intestinal distension regulates the excitability of ENS circuits via mechanosensitive channels.
