Efficient sweat secretion decreases negative, and increases positive skin potential responses

Abstract

This study investigated the effect of sweat secretion on negative and positive skin potential responses. In Experiment 1, the relationship between the rate of negative skin potential amplitude in the skin potentialresponse (negative component rate)and the latency from the onset of theskin potential response to the sweatingresponse(SPR-sweating latency) were determined.Six students participated in Experiment1.Student's t-test indicated thatthelower was the negative component rate,the shorter was the SPR-sweating latency.This result suggests that the less negative component shortens the SPR-sweating latency.In Experiment2,the influence of the amount of sweat in the ducts onthe positive component was investigated to clarify whether the presence of sweat in the ducts was important for the efficient secretion of sweat. Eight students participated in Experiment2.It was found that when the ducts were saturatedwith sweat,the positive monophasic wave increased.Based on these results,we have developed an efficient-sweating model.
