弱微波场对神经纤维影响的非热机制
Non-Thermal Mechanism of Weak Microwave Fields Influence on Nerve Fiber
摘要:
提出了弱微波场作用于神经纤维的非热机制。它示出,在约30 - 300 GHz的范围内,有强烈明显的共振与激励的超声波振动的膜作为结果与电磁辐射的相互作用。这些振动产生声压,其可导致蛋白质跨膜通道的重新分布,并且因此改变神经网络的轴突中的动作电位激发的阈值。分析了电磁微波辐射对髓鞘神经纤维的各个特定区域的影响:朗维尔结,以及所谓的初始段-神经元丘和覆盖有髓鞘层的轴突的第一部分之间的区域。结果表明,起始段是有髓神经纤维最敏感的区域,动作电位通常从该区域开始。
英文摘要:
We propose a non-thermal mechanism of weak microwave field impact on a nerve fiber. It is shown that in the range of about 30 - 300 GHz there are strongly pronounced resonances associated with the excitation of ultrasonic vibrations in the membrane as a result of interaction with electromagnetic radiation. These vibrations create acoustic pressure which may lead to the redistribution of the protein transmembrane channels, and, thus, changing the threshold of the action potential excitation in the axons of the neural network. The influence of the electromagnetic microwave radiation on various specific areas of myelin nerve fibers was analyzed: the nodes of Ranvier, and the so-called initial segment - the area between the neuron hillock and the first part of the axon covered with the myelin layer. It is shown that the initial segment is the most sensitive area of the myelined nerve fibers from which the action potential normally starts.
