Gastric emptying depends on functional coupling of slow waves between the corpus and antrum, to allow slow waves initiated in the gastric corpus to propagate to the pyloric sphincter and generate gastric peristalsis. Functional coupling depends on a frequency gradient where slow waves are generated at higher frequency in the corpus and drive the activity of(More)
BACKGROUND Animals carrying genetic mutations have provided powerful insights into the role of interstitial cells of Cajal (ICC) in motility. One classic model is the W/W(V) mouse which carries loss-of-function mutations in c-kit alleles, but retains minimal function of the tyrosine kinase. Previous studies have documented loss of slow waves and aberrant(More)
