Fig. 1. (A) Duodenojejunal manometric tracing showing the presence of a burst of contractions (asterisk, sixth tracing) and of discrete clustered contractions (last tracing). The first 5 recording points (spaced 2 cm apart) are in the antrum and proximal duodenum, and the last 2 (spaced 12 cm apart) in the distal duodenum and jejunum. (B) Another recording period showing the presence of a burst of contractions (asterisk) and of discrete clustered contractions (arrow). Recording points as in (A). (C) Only this trace, obtained just before the end of the session, shows the normally propagated activity front during a 6-hour fasting period.
