Molecular communications provide an attractive opportunity to precisely regulate biological signaling in nano-medicine applications of body area networks. In this paper, we utilize molecular communication tools to interpret how neural signals are generated in response to external stimuli. First, we propose a chain model of molecular communication system by considering three types of biological signaling through different communication media. Second, communication models of hormonal signaling, Ca 2 + signaling and neural signaling are developed based on existing knowledge. Third, an amplify-and-forward relaying mechanism is proposed to connect different types of signaling. Simulation results demonstrate that the proposed communication system facilitates the information exchange between the neural system and nano-machines, and suggests that proper adjustment can optimize the communication system performance.
分子通信为精确调节生物信号提供了一个有吸引力的机会，在体域网的纳米医学应用中具有重要意义。在本文中，我们利用分子通信工具来解释神经信号如何对外界刺激做出响应。首先，我们通过考虑三种不同通信介质的生物信号，提出了一个分子通信系统的链式模型。其次，基于现有的知识，我们建立了激素信号、Ca 2+ 信号和神经信号的通信模型。然后，提出了一种放大转发中继机制来连接不同类型的信号。仿真结果表明，所提出的通信系统促进了神经系统和纳米机器之间的信息交换，并表明适当的调整可以优化通信系统的性能。
