[Electromyographic correlations of ingesta movements in the proximal digestive tract of the hen].

Digesta transit along the oesophagus, crop and stomach has been determined by the migration of spike bursts correlated with cineradiographic observations in hens fitted with chronically implanted electrodes. The passage of digesta along the oesophagus corresponded to the propagation of isolated spike bursts. During crop filling, the activity was weak, its emptying being mediated by migrating repetitive spike bursts. A cyclically recurring electrical activity was noted for the glandular and muscular stomachs and the duodenum; their motility is described in relation to digesta movements.
