Summary: This protocol describes a process for the measurement of electrical stimulation-induced effects on duodenal motility in young adult Sprague-Dawley rats. Signals recorded from strain gauges attached to the proximal duodenal surface were used to measure the effect of stimulation by patch electrodes implanted at multiple sites across the rat stomach in an acute anesthetized preparation. The effect of stimulation was quantified as the ratio of various motility assessments during and after stimulation vs. before stimulation, and the data was used to create a functional map of duodenal motor response to localized gastric stimulation.
