Abstract
1. Isolated taenia coli of guinea pig was used for recording the spontaneous spike discharge intracellularly.
2. Results obtained from the present experiments indicate that the interaction mechanism must be existent between adjacent cells and by this mechanism, excitation can pass from cell to cell.
3. This mechanism of interaction is easily destroyed (this condition is the dissociation), but restored again.
4. The feature of the spike patterns before and after dissociation could be clearly represented in a diagram (mean interval-standard error diagram).
