Mimicking axon-growth by a bio-inspired memristive circuit — Sebastian Jenderny, •Bakr Al Beattie, and Karlheinz Ochs — Ruhr University Bochum, Chair of Digital Communication Systems, Bochum, Germany

Hardware implementations of neuronal networks are already very powerful. In terms of e.g. energy efficiency, however, they are still far inferior to biological neuronal networks. For this purpose, a better understanding of the general principles that shape these networks can contribute to the development of improved electrical circuits. One principle often neglected is the growing of axons, which has, up to now, only been considered for technical abstract circuit realizations. In this context, our aim is to develop a more bio-inspired circuit model mimicking axon growth in a way that can be compared to the biological process. To this end, we utilize Morris-Lecar oscillators as axon segments and memristors for implementing the growth mechanism. A wave digital emulation then successfully verifies our circuit approach for an axon growth example taken from biology.
