This study was designed to examine the reliability of spontaneous electrodermal activity (EDA) as a function of the stages of sleep and waking in freely moving cats. Five adult cats were observed during waking--sleep sessions. The results show that: (a) for all stages, the reliability of EDA is slightly higher for amplitude of SSPRs than for frequency; (b) during drowsiness, a maximum of reliability is observed, as is a slight decrease during slow wave sleep; during paradoxical sleep, reliability decreases greatly to below that of the waking level; (c) the reliability of spontaneous EDA appears to be higher in waking cats than that quoted for human subjects. These results are discussed with reference to individual characteristics and state variables.
本研究旨在检测自由活动的猫在睡眠和清醒阶段自发皮肤电活动（EDA）的可靠性。在清醒 - 睡眠期间观察了五只成年猫。结果表明：（a）在所有阶段，SSPRs幅度的EDA可靠性略高于频率；（b）在困倦期间，观察到可靠性最高，在慢波睡眠期间略有下降；在异相睡眠期间，可靠性大幅下降至低于清醒水平；（c）清醒猫的自发EDA可靠性似乎高于人类受试者的相关报道。结合个体特征和状态变量对这些结果进行了讨论。
