The Artificial Axon


Action potentials are the voltage spikes produced in the neuron. Their generation and regulation have been studied in living cells for close to 100 years. The objective of the Artificial Axon is to take this most interesting of dynamical systems out of the cell and into an artificial setting. Create cell-free action potentials, so to speak. The system is based on the fundamental biological components – ion channels, lipid bilayers – assembled in vitro. It displays the basic electrophysiology of neurons: threshold response and integrate-and-fire dynamics. I will present the system, its shortcomings, and discuss future directions. Namely, we would like to think of the Artificial Axon as the basic unit of an ionic network.
