Being the primary mean of translating the chemical signal into the electric signal in neuromuscular junction, the nACh receptor is the first kind of ligand-gated channel that its kinetic structure has been known clearly. The next problem is to know quantitatively how it works in a living system. In this paper, we construct a piece-wise deterministic process to mimic the membrane voltage fluctuation driven by a single nACh receptor. The power spectrum of the voltage fluctuation is solved analytically, which reveals the $1/{\omega }^4$-type noise.

由单个nACh受体驱动的膜电压的功率谱

nACh受体是将神经肌肉接头中的化学信号转化为电信号的主要手段，是第一类已知其动力学结构的配体门控通道。下一个问题是定量了解其在生命系统中的工作方式。在本文中，我们构建了一个分段确定性过程，以模拟由单个nACh受体驱动的膜电压波动。解析了电压波动的功率谱，揭示了$\mathrm{1个}/{\omega }^4$型噪音。
