The nervous system holds a central position among the major in-body networks. It comprises of cells known as neurons that are responsible to carry messages between different parts of the body and make decisions based on those messages. In this work, further to the extensive theoretical studies, we demonstrate the first controlled information transfer through an in vivo nervous system by modulating digital data from macro-scale devices onto the nervous system of common earthworms and conducting successful transmissions. The results and analysis of our experiments provide a method to model networks of neurons, calculate the channel propagation delay, create their simulation models, indicate optimum parameters such as frequency, amplitude and modulation schemes for such networks, and identify average nerve spikes per input pulse as the nervous information coding scheme. Future studies on neuron characterization and artificial neurons may benefit from the results of our work.
神经系统在体内主要网络中占据中心位置。它由称为神经元的细胞组成，负责在身体的不同部位之间传递信息，并根据这些信息做出决策。在这项工作中，除了广泛的理论研究外，我们还通过调制来自宏观设备的数字数据到常见蚯蚓的神经系统上，并成功进行传输，展示了通过体内神经系统进行首次受控信息传输。我们实验的结果和分析提供了一种方法来模拟神经元网络，计算通道传播延迟，创建它们的模拟模型，为这些网络指示最佳参数，如频率、幅度和调制方案，并确定每个输入脉冲的平均神经尖峰作为神经信息编码方案。未来对神经元特性和人工神经元的研究可能会受益于我们工作的结果。
