Abstract

Electron microscopy of the cerebral cortex in cats and monkeys following transcranial micropolarization (TCMP) demonstrated ultrastructural changes whose degree was dependent on the electric current intensity and the stimulation period. In the focus of stimulation the current affected the brain tissue directly, different elements of the cerebral cortex showing unegual sensitivity to various TCMP regimens. The glia was the first to respond, then the neuronal bodies, and the last -- the synaptic structures. In the areas distant from the TCMP focus synaptic components altered first. The ultrastructural changes revealed were not of pathological character.

摘要

对经颅微极化(TCMP)处理后的猫和猴的大脑皮质进行电子显微镜检查,结果显示超微结构发生了变化,其程度取决于电流强度和刺激时间。在刺激焦点处,电流直接影响脑组织,大脑皮质的不同成分对各种TCMP方案的敏感性不同。神经胶质最先做出反应,然后是神经元胞体,最后是突触结构。在远离TCMP焦点的区域,突触成分最先发生改变。所揭示的超微结构变化并非病理性的。
