Electrodermal Activity (EDA) was measured in 55 subjects during (1) an alarm reaction, (2) mental load, and (3) physical load. In 34 subjects, not only was a transient response observed, but also, oscillatory patterns characterizing short term variations of EDA. The durations of these oscillations varied between 3-16 s. Most commonly, they were approximately within the frequency range of respiration, or lower, at about 0.1 Hz. The EDA-rhythms were also related to the arterial blood pressure. They were, however, not strictly synchronized with respiration or with the blood pressure waves. We conclude that assessment of EDA in combination with fluctuations of the heart rate, and also, if possible, arterial blood pressure, may turn out to be a useful tool in the evaluation of the interaction between different regulatory processes that are realized by the common brainstem system.
在55名受试者中测量了皮肤电活动（EDA），测量时段包括：（1）警报反应期，（2）精神负荷期，以及（3）身体负荷期。在34名受试者中，不仅观察到了瞬态反应，还观察到了表征EDA短期变化的振荡模式。这些振荡的持续时间在3 - 16秒之间变化。最常见的是，它们大致在呼吸频率范围内，或更低，约为0.1赫兹。EDA节律也与动脉血压有关。然而，它们与呼吸或血压波并不严格同步。我们得出结论，结合心率波动以及（如果可能的话）动脉血压来评估EDA，可能会成为评估由共同脑干系统实现的不同调节过程之间相互作用的有用工具。
