Research On Molecular Communication Technology Based On Neuron

The molecular communication based on neurons is a communication technology that makes use of the biochemical molecules in the neural cells as the information carrier for interconnecting the nanomachines to form distributed nanonetwork.In this paper,we studied the change of Ca²⁺concentration in nerve cells and its influence on the membrane potential of neurons to accomplish the encoding of neuron information.In this paper,we cultured mouse neural cells on the surface of the MEA?microelectrode array?chip,and then through the connection of the external signal acquisition device and the lead wire on the microelectrode chip to obtain the waveform of the neural cell electrical signal on the computer,finally the signal is de-noised to get the obvious peak value.In order to verify the consistence with the experiment and code the information,we studied the effect of changes in neuronal ion channels on the release of cell membrane potential.Through the modeling of Ca²⁺channels in nerve cells,the relationship between Ca²⁺channel changes and membrane potential distribution was obtained.Finally,the experimental and simulated data are summarized to make use of nerve cells produces different peak waveforms at different Ca²⁺concentrations,and the peak signal is encoded based on digital baseband modulation.This paper encodes the peak signal of membrane potential under the influence of Ca²⁺in neurons,which not only provides a way for the study of micro-nanoscale communication,but also provides a theoretical basis for the nanomachine to send data.
