Abstract

Mechanism of EEG formation was studied in terms of "EEG quantum". The "quantum" approach gives the same results as that based on the cell dipole concept. EEG is created by partially correlated activity of vertically oriented pyramide neurons of the cortex; the value of correlation coefficient between EEG of two points of the cortex and its dependence on interelectrode distance are determined by an increased level of intercellular correlation in the cortex microvolumes by the value of intercellular correlation drop on the borders of these microvolumes and by the dimensions of these microvolumes. The advantage of the "quantum" approach lies in the fact that final expressions include the mean values of correlation coefficients between impulse currents generated by the cortical cells, i. e. the parameters which can be measured experimentally.

摘要

从“脑电图量子”的角度研究了脑电图形成的机制。“量子”方法得出的结果与基于细胞偶极子概念的结果相同。脑电图是由皮质垂直定向的锥体神经元的部分相关活动产生的;皮质两点脑电图之间的相关系数值及其对电极间距离的依赖性,由皮质微体积中细胞间相关性增加的水平、这些微体积边界上细胞间相关性下降的值以及这些微体积的尺寸决定。“量子”方法的优点在于,最终表达式包含了由皮质细胞产生的脉冲电流之间相关系数的平均值,即可以通过实验测量的参数。
