Abstract

The data obtained in the paper showed that complex dynamics of changes of spatial-temporary situation of heterocomponent thalamocortical responses (TCR) at passing the sensorimotor cortex (SMC) was conditioned by the properties of electrogenesis of each TCR component, age and frequency of stimulation of ventroposterolateral (VPL) thalamus nucleus transformation of electric profile of the second positive component (PC-2) of the TCR at passing SMC might testify to algebraic summation in this component of bioelectric processes of several generation sources (invertible and non-invertible PC-2). The revealed properties of ontogenetic dynamics of the bioelectric fields profiles of the third negative component (NC-3) of the TCR might be the consequence of the age stages of the development and change of embryonal mechanisms of electrogenesis of the definitive ones in extremely similar negativities.

摘要

该论文中获得的数据表明,异质丘脑皮质反应(TCR)在通过感觉运动皮层(SMC)时空间 - 时间情况变化的复杂动态,是由每个TCR成分的电发生特性、年龄以及腹后外侧(VPL)丘脑核刺激频率所决定的。TCR的第二个正成分(PC - 2)在通过SMC时电轮廓的转变,可能证明了该成分中多个产生源(可逆和不可逆PC - 2)生物电过程的代数总和。TCR第三个负成分(NC - 3)生物电场轮廓个体发育动态的揭示特性,可能是发育年龄阶段以及最终在极其相似的负性中电发生胚胎机制变化的结果。
