The behavioral changes depending on the intensity of intestinal and skin stimuli were studied in rats. The reactions to the electric stimulation of the gut mucosa as well as of the abdominal skin were classified into four categories. The thresholds were calculated by interpolation from intensity-frequency curves. The behavioral effects of the external and the internal stimulation have been compared. The appropriate criteria for evaluating the thresholds and the consequences of the sigmoid shape of the curves were also discussed.
