In conscious dogs, contractile and myoelectric activity was recorded from force transducers and monopolar electrodes chronically implanted in the serosal surface of the proximal and distal stomach. Periodic activity during fasting was characterized at each site. Proximally, activity fronts consisted of a series of regular large-amplitude contractions,(More)
An inexpensive four-channel data logger for recording gastrointestinal potentials is described. A 512 K bytes memory and a sampling speed of 1.25 Hz per channel is adequate for these potentials and permits recordings for up to 27 hours. The small size and light weight allow the device to be carried in a pocket so that recordings can be made while the(More)
