Changes of correlation coefficients and coherence of the delta-, theta- and alpha-rhythms were studied between the somatosensory, motor and visual neocortex areas, dorsal hippocampus and dentate fascia at stimulation frequencies of the midbrain reticular formation from 60 to 1000 imp/s. It was shown that correlation coefficient between the structures studied increased at 60-200 imp/s and decreased at the further increase of stimulation frequency. In pairs with the visual area the correlation coefficient changed but little. The delta-rhythms coherence tended to decrease with the increase of stimulation frequency. Coherence of the theta-rhythms between the neocortical areas and the hippocampus increased with the increase of stimulation frequency up to 200 imp/s and decreased at higher frequency stimulation while in pairs of these areas with the dentate fascia it continued to rise with the increase of stimulation frequency up to 1000 imp/s. The coherence of the alpha-rhythms was almost unchanged at 60-200 imp/s and mostly had an increase at higher frequency stimulation.
在中脑网状结构60至1000次/秒的刺激频率下，研究了体感、运动和视觉新皮层区域、背侧海马体和齿状筋膜之间δ波、θ波和α波的相关系数及相干性变化。结果表明，所研究结构之间的相关系数在60 - 200次/秒时增加，在刺激频率进一步增加时降低。与视觉区域配对时，相关系数变化不大。δ波的相干性倾向于随刺激频率的增加而降低。新皮层区域与海马体之间θ波的相干性随刺激频率增加至200次/秒而增加，在更高频率刺激时降低，而在这些区域与齿状筋膜配对时，其相干性随刺激频率增加至1000次/秒持续上升。α波的相干性在60 - 200次/秒时几乎不变，在更高频率刺激时大多增加。
