Abstract

Disclosed are devices, systems and methods for monitoring electrophysiological function from anatomical structures, including gastric slow-waves in high resolution electrogastrograms. In some aspects, a device includes an electrophysiological sensor structured to include an array of electrodes spatially arranged on a substrate and operable to acquire electrophysiological signals to obtain time-series data, the electrodes spaced about an anatomical structure on the subject's body with at least one electrode placed with reference to an anatomical landmark and other electrodes of the electrode array each placed at a spatial distance from another of the surface electrodes; and a data processing unit to process spatially resolved time-series data based on the electrophysiological signals to determine wave propagation parameters including direction and/or speed for each time point of interest of the acquired electrophysiological signals, in which the wave propagation parameters are associated with a physiological function of the anatomical structure of the subject's body.
