The short-lasting intermediate stage of sleep occurring between slow wave sleep and paradoxical sleep showed frontal cortex spindles of higher amplitude and longer duration than during slow wave sleep, and hippocampal theta rhythm of lower frequency than during paradoxical sleep. During the intermediate stage, the mesencephalic reticular arousal threshold was slightly higher than during the slow wave sleep and much lower than in the paradoxical sleep. Thus, following this central reactivity test, the intermediate stage seems to be functionally nearer the slow wave sleep than the paradoxical sleep.
在慢波睡眠和异相睡眠之间出现的短暂中间睡眠阶段，额叶皮质纺锤波的振幅高于慢波睡眠期间，持续时间也更长，海马体θ节律的频率低于异相睡眠期间。在中间阶段，中脑网状激活阈值略高于慢波睡眠期间，远低于异相睡眠期间。因此，经过这种中枢反应性测试后，中间阶段在功能上似乎比异相睡眠更接近慢波睡眠。
