High resolution (multi-electrode) electrical mapping has become a prominent technique for investigating the propagation of electrical activity in the gastrointestinal (GI) tract. This technique involves the placement of dense arrays of many electrodes over the surface of the tissue, in order to reconstruct the spread of electrical activation in accurate spatiotemporal detail. Multi-electrode mapping can be performed in-vivo and in-vitro in a variety of animal models, and clinical methods for human mapping are also advancing. This chapter reviews the current status of GI multi-electrode mapping, with a particular focus on the principles of extracellular recordings, the design of mapping devices, the discrimination of artifacts, and the practical considerations for successful experimental work. Potential future directions for the field are considered.
