A comparison of the organization of longitudinal and circular contractions during pendular and segmental activity in the duodenum of the rat and guinea pig

Abstract

Localized contractions during segmental and pendular activity had some features of the spike patches that are normally associated with slow wave propagation. However, the commencement of propagation following administration of neural blocking agents and cholinergic inhibitors indicates their localization is maintained by inhibitory elements of the enteric nervous system.
