1. An electrical circuit for interfacing two or more neuron circuits of a neural system, comprising: a memristor connected between a first neuron circuit and a second neuron circuit; a pre-synaptic interface circuit connecting the first neuron circuit with the memristor; and a post-synaptic interface circuit connecting the memristor with the second neuron circuit, wherein the pre-synaptic interface circuit and post-synaptic interface circuit include high-impedance terminations.
