Electrical spike potentials from the canine duodenum have been recorded from intramuscular implanted and intraluminal suction electrodes. There was a significantly greater amplitude of the spike potentials recorded from implanted electrodes, otherwise the potentials were identical in number, duration and time of onset. Thus spike potentials recorded from suction electrodes, as used in clinical motility studies, accurately represent the event within the muscular layer.
