Electrical Activity of Cat Intestine Following Defunctionalization
Chronically recorded electrical activity of cat intestine consists of slow waves (SW’s), spike potentials (SP’s), and migrating spike complexes (MSC’s). SW’s and SP’s are similar to those occurring in other species. MSC’s, although unique to the cat in some respects, exhibit certain properties of migrating myoelectric complexes (MMC’s). For example, the MSC migrates caudally at a velocity of ca 1 mm/sec (1). Furthermore, it occurs primarily during the fasted state, and it can traverse a region of transection and anastomosis (2).
