A study was made on 13 subjects in a state of rest and mental stress, of interconnection between the level of distant biopotential synchronization of separate cortical zones (which is a criterion of the rate of brain activation) and the spectral power of EEG frequencies. There is a statistically significant positive correlation between the first parameter and the energy of low frequency activity band (delta-theta). At the same time similar dependences for the alpha- and beta-rhythms are negative and topographically less spread. The coherence function likewise increases during mental stress for the low-frequency band alone. The data obtained point to the special role of low-frequency rhythms in the transmission of excitation over the cortex and support the significance of the alpha-rhythm in providing for the mechanisms involved in the control of homeostasis.
对13名处于休息和精神应激状态的受试者进行了一项研究，研究单独皮质区的远距离生物电位同步水平（这是大脑激活速率的一个标准）与脑电图频率的频谱功率之间的相互关系。第一个参数与低频活动带（δ-θ）的能量之间存在统计学上显著的正相关。同时，α和β节律的类似相关性为负，且在地形上分布较窄。相干函数同样仅在精神应激期间低频带增加。所获得的数据表明低频节律在皮质兴奋传递中的特殊作用，并支持α节律在维持体内平衡控制机制中的重要性。
