Atypical slow waves generated in gastric corpus provide dominant pacemaker activity in guinea pig stomach

Hashitani, Hikaru; Garcia-Londono, Pilar; Hirst, George; Edwards, Frank


When intracellular recordings were made from the circular layer of the intact muscular wall of the isolated guinea pig gastric corpus, an ongoing regular high frequency discharge of slow waves was detected even though this region lacked myenteric interstitial cells. When slow waves were recorded from preparations consisting of both the antrum and the corpus, slow waves of identical frequency, but with different shapes, were generated in the two regions. Corporal slow waves could be...[Show more]
