It was found in chronic experiments in cats, using the recording of local blood flow and oxygen tension (pO2) in the anterior and posterior hypothalamus in the sleep-wakefulness cycle, that when the phases of sleep are alternated, the changes in these parameters are in different directions: the level of blood flow and the frequency of fluctuation of the pO2 during paradoxical sleep increase in the posterior hypothalamus, while they decrease in the anterior hypothalamus. On the other hand, the opposite pattern is observed during slow-wave sleep. The multidirectionality of the changes in local blood flow level and in the frequency of fluctuations of pO2 in one and the same sleep phase indicate that they are of local origin and must be governed by functional-metabolic shifts in these structures; the functional state of the posterior hypothalamus during paradoxical sleep is assessed on this basis.
在对猫进行的慢性实验中，通过记录睡眠-觉醒周期中下丘脑前部和后部的局部血流和氧分压（pO2）发现，当睡眠阶段交替时，这些参数的变化方向不同：在异相睡眠期间，下丘脑后部的血流水平和pO2波动频率增加，而下丘脑前部则降低。另一方面，在慢波睡眠期间观察到相反的模式。同一睡眠阶段局部血流水平和pO2波动频率变化的多向性表明它们是局部起源的，并且必定受这些结构中功能-代谢变化的支配；基于此评估异相睡眠期间下丘脑后部的功能状态。
