Roles of three distinct neurogenic motor patterns during pellet propulsion in guinea‐pig distal colon

Key points Enteric neural circuits enable isolated preparations of guinea‐pig distal colon to propel solid and fluid contents by a self‐sustaining neuromechanical loop process. In addition there are at least three neural mechanisms which are not directly involved in propulsion: cyclic motor complexes, transient neural events and distal colon migrating motor complexes. In excised guinea‐pig colon we simultaneously recorded high resolution...
