The Impedance of Spiking Neurons Coupled by Time?Delayed Interaction

The synchronization of populations interacting spiking neurons is a topic interest for understanding the operation brain and developing oscillatory-based biomimetic computation. analysis by models such as Hodgkin–Huxley (HH) FitzHugh–Nagumo (FHN) based on electrical electrochemical concepts. application small-signal AC impedance equivalent circuit methods promising tool fabrication artificial synapses with memristor technologies neuromorphic computation sensory-motor autonomous systems. time domain spectroscopy two FHN coupled delay related to propagation action potentials developed. Depending coupling strength constant, become synchronized, in phase opposition weak coupling, alternating spike packets strong interaction. delayed interaction introduces new element circuit. A oscillatory that causes curling basic spectral patterns associated onset limit cycle presence Hopf bifurcations found. pattern appealing an experimental determine experimentally extent between neurons.
