Extracellular recordings from the stomach faithfully record slow-wave activity detected using intracellular microelectrodes.

This article discusses the propagation of slow waves in the stomach and the use of extracellular recordings to study this phenomenon. The authors conducted a study using high-resolution mapping and extracellular electrode arrays in anesthetized rats to investigate how slow waves propagate along the distal stomach. They found that slow waves propagate in an antegrade direction, with some regional variation, and that the amplitude and velocity of propagation vary in different regions of the stomach. The study also confirmed that extracellular recordings are a reliable technique for studying gastric slow waves. Overall, this research provides valuable insights into the coordination of gastric peristalsis and the characteristics of slow wave propagation in the stomach. [Extracted from the article]
