In some areas, computing technology may be expected to benefit from the selective imitation of biological neural networks. This paper summarizes experimental results obtained in the development ofan artificial electro-chemical synapse, based on copper sulfate as the primary electrolytic component, and subsequent progress towards miniaturization, including reduction to an integrated circuit, substitution of a solid electrolyte, and appropriate packaging. The device exhibits many of the characteristics of a neurobiological synapse and shows promise as a component of extended serial and parallel networks responsive to chemical as well as electrical signals, as in animal brains. An interpretation of the experimental work is offered based on mathematical modelling and computer simulation.
