Electromyogram of the Cat Colon and Colonic Flow

  • J. Christensen


The electromyogram of the cat colon is not a subject I planned to study initially but rather an area that developed as a result of a casual observation about five years ago. I will summarize in this paper the work done since then by a group of people who have collaborated in my laboratory, Caprilli (Christensen, et al., 1969), Wienbeck, Anuras (Christensen, et al., 1974), Hauser (Christensen & Hauser, 1971a, 1971b; Christensen, et al., 1972), and Freeman (Christensen & Freeman, 1972). All of this work has been published and I apologize for not having anything new and unpublished to present today.
