Transmural potential difference at the level of the upper esophageal sphincter in man

Abstract

Using an improved method of recording transmural potential difference, a fall of potential difference was demonstrated at the level of the high pressure zone of the upper esophageal sphincter in normal subjects. The level where this negative deflection of potential difference occurs corresponds to the area where, in the upper esophagus, glands resembling… (More)
