Phasic clasp-overlying activity may drive esophageal contractions; leaves open its role in human GEJ motility pending in vivo confirmation.
Several muscles of the human esophagus and GEJ manifest repetitive contractions in vitro, particularly the longitudinal muscle overlying the clasp muscle fibers, driven by electrical slow waves.
Preiksaitis et al. (1995) studied this question.
