Study of dominating spectral maxima in delta-, theta- and alpha-ranges of the electrical activity of rabbits' neocortex and hippocampus showed that an increase of the frequency of the mesencephalic reticular formation stimulation from 60 to 200 imp/s led in both structures to an enhancement of the theta-rhythm (up to 130% in the neocortex and 147% in the hippocampus) and suppression of delta- and alpha-activity (correspondingly up to 67 and 34% in the neocortex and 37 and 48% in the hippocampus) with subsequent weakening of this effect at frequency increase up to 1000 imp/s. In the hippocampus, the reticular stimulation was more effective with respect to the theta- and delta-rhythms, and in the neocortex--with respect to the alpha-rhythm. In both structures the theta-rhythm amplitude changed less than the amplitude of the delta- and alpha-activities. Dependence of the amplitude of dominating rhythms on intensity of reticular formation stimulation differed from the analogous frequency dependence of the same rhythms.
对家兔新皮质和海马体电活动的δ波、θ波和α波范围内的主导频谱最大值的研究表明，中脑网状结构刺激频率从60次/秒增加到200次/秒时，在这两种结构中均导致θ节律增强（新皮质中高达130%，海马体中高达147%），以及δ波和α波活动受到抑制（新皮质中相应高达67%和34%，海马体中为37%和48%），随后在频率增加到1000次/秒时这种效应减弱。在海马体中，网状刺激对θ波和δ波节律更有效，而在新皮质中，对α波节律更有效。在这两种结构中，θ波节律的振幅变化小于δ波和α波活动的振幅。主导节律的振幅对网状结构刺激强度的依赖性不同于相同节律的类似频率依赖性。
