Bio-Inspired Design of Superconducting Spiking Neuron and Synapse

The imitative modelling of processes in the brain living beings is an ambitious task. However, advances complexity existing hardware models are limited by their low speed and high energy consumption. A superconducting circuit with Josephson junctions closely mimics neuronal membrane channels involved operation sodium-potassium pump. dynamic such a system characterised duration picoseconds level attojoules. In this work, two biological neuron studied. New modes identified, including so-called bursting mode, which plays important role neural networks. possibility switching between different situ shown, providing control system. synaptic connection that short-term potentiation synapse developed demonstrated. Finally, simplest two-neuron chain comprising proposed bio-inspired components simulated, prospects biosimilars briefly discussed.
