通过植入大脑的电极进行电刺激，确定猫在特定5阶段睡眠-觉醒分类的不同阶段的觉醒阈值。只有在警觉觉醒（W-1）阶段刺激时引起定向行为的区域才用于觉醒阈值研究。与W-1相比的阶段是W-2、SWS[慢波睡眠]-1、SWS-2和REM [快速眼动]睡眠。从W-2到REM睡眠，从一个阶段到下一个阶段，觉醒阈值呈阶梯式递增。结构之间存在一些差异，但阈值增量是一致的，支持5阶段睡眠-觉醒分类的有效性。
Awakening thresholds during the different stages of a particular 5-stage sleep-waking classification in the cat were determined by electrical stimulation through electrodes implanted in the brain. Only areas from which orienting behavior was elicited when stimulated during the alert waking (W-1) stage were used for the awakening threshold studies. The stages compared with W-1 were W-2, SWS[slow wave sleep]-1, SWS-2 and REM [rapid eye movement] sleep. There were stepwise increments in the awakening thresholds from 1 stage to the next in the predicted order from W-2 to REM sleep. There was some variation between structures, but the threshold increments were consistent and support the validity of the 5-stage sleep-waking classification.
