Experimental studies were performed on the mechanism of intestinal movement electromyographically. The action potentials were recorded from intestinal wall of mongrel dogs with various surgical conditions. Frequency of spike-burst was investigated as a pattern of electromyogram. In control group, frequency of spike-burst of upper jejunum was 17.6 cycles/min. and lower ileum was 12.9 cycles/min. Changes of spike-burst frequency with transection and end-to-end anastomosis were observed. Proximal to the anastomosis, the average frequency was 17.5 cycles/min and distal to it fell in 13.4 cycles/min. The recovery to normal frequency was incomplete even 14 months after operation. The transection of intestinal tract has brought the decrease of spike-burst frequency in its distal portion, but no considerable changes were observed in further transection of its distal canal. The frequency of spike-burstwas not at all affected by the section of nerves in mesentery. Thelongitudinal section was ineffective to produce the change of spike-burst frequency.
