CMOS implementation of a pulse-coupled neuron cell

Recent applications of pulse-coupled neural networks have demonstrated the need for a simple pulse-coupled neuron circuit which can easily be implemented in CMOS technology. The proposed cell uses a positive feedback circuit with two capacitors. One capacitor corresponds to the external sodium ion potential, and the other to the internal potassium ion potential. This cell body circuit is also used as a neural segment in an artificial axon. When linked by large resistors, these neural segments display many properties expected in a biological axon.
