Spatiotemporal Mapping of Motility in Ex Vivo Preparations of the Intestines

Overview

This article presents a protocol for generating and analyzing spatiotemporal maps (STmaps) of intestinal motility using the GastroIntestinal Motility Monitoring (GIMM) system. The technique allows for the visualization of complex motility patterns in ex vivo intestines, enhancing our understanding of intestinal wall movements.
