Building Electronic ML Neuron Networks And Its Analysis

There are many neurons in the neuron system and neurons are the basis of neuronscience. It costs too much to do biological experiments on neurons, and usually is hard to achieve. When doing mathematical simulation in neural network analysis, computational speed becomes the main limt. Neuronmphic which investigates the realization of real neuron using electronic circuit is growing fast and has attracted more attention recently. Electronic neurons can provide an experiment platform with the real-time scale and high computation speed. The electronic neuron is very usefull in research of dynamics of neuron networks and bionics. Electronic neuron is important to some kinds of nerve disease.In this thesis, the electronic neuron is implemented based on analysis of ML model and the bifurcation of the Morris-Lecar model is analyzed using the circuit. Bursting neurons are achieved by introducing a slow driving current. The parameter of slow driving current has a big effect on the burster. Chemical synapse is the most important connect substance in neuron systerm. Chemical synapses have big effect on neuron siginal producing and conducting. Exciting and inhibitory synapses are implemented in the work. The mechanism of neuron synchronization rhythm has been analyzed. Most meaningfull, the spiking competition in two reciprocally inhibitory electronic neurons is analyzed, and how the exter current affect the system is analyzed clearly.Several exciting and inhibitory neuron networks are built, and analyzed carefully. Central Pattern Generator (CPG) is a kind of special networks which is made of several function identified neurons. It can produce some rhythm signal. The lobster stomatogastric pyloric rhythm generator is one kind of CPG. It is implemented and how it can maintain phase is analyzed briefly. At last, the neuron networks are used to drive motors. This work can show the action of the animal briefly.The result of this thesis can be used in the large neuron networks to analyse the essence of action potential conducting and process.
