Origin, propagation and regional characteristics of porcine gastric slow wave activity determined by high‐resolution mapping

Background  The pig is a popular model for gastric electrophysiology studies. However, its normal baseline gastric activity has not been well characterized. High‐resolution (HR) mapping has recently enabled an accurate description of human and canine gastric slow wave activity, and was employed here to define porcine gastric slow wave activity.
