摘要
研究神经元细胞自身性质对动作电位在其内部传输的透射率和反射率.根据神经元细胞的实际情况建立物理模型,将动作电位模拟看作电磁波,利用麦克斯韦方程组推导动作电位传输的波动方程,由边界连续性条件推导求解得出动作电位在神经元细胞中传输的透射率和反射率,再利用matlab软件进行模拟运算得出动作电位的透射率和反射率.研究结果表明神经元细胞中水分含量越高,动作电位在神经元细胞中传输的透射率越大.这有利的说明了为什么随着细胞中水分流失,人的行动迟缓,生命体衰老的生物学现象.神经元细胞在正常含水量范围内,其动作电位传输的透射率及反射率随着神经元细胞树突本身长度的增加,基本上均呈现单调减少行为,而随神经元细胞轴突长度的增加,呈类周期性变化,但其振幅在逐渐减小.研究结果也间接说明生物学领域的动作电位是一种电磁波.
In this paper, the transmittance and reflectance of action potentials transmitted in neurons by their own properties was studied. The physical model was established according to the actual situation of neuron cells, and the action potential simulation was regarded as electromagnetic ware. The equation of action potential transmission was derived by Maxwell`s equations, and the transmittance and reflectance of action potential transmission in neuron cells were derived and solved by boundary continuity condition. Then matlab software was used to simulate the transmission and reflectance of the action potential. The results showed that the higher the water content in neurons, the higher the transmission rate of action potential in neurons. This helps to explain the biological phenomenon of why living things age and people move more slowly as water is lost from their cells. In the normal water content range, the transmission of neuronal cells basically decreased monotonically with the increase of the length of dendritic cells, and showed a quasi-periodic change with the increase of the length of neuronal axons, but the amplitude gradually decreased. The results also indirectly indicate that the action potential in field of biology is a kind of electromagnetic ware.
