Herein, threshold switching in oxyvanite (V\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>5<\/jats:sub>\n                    ) memristors and their application as a leaky integrate\u2010and\u2010fire (LIF) neuron are explored. The spiking response of individual neurons is examined as a function of circuit parameters, input pulse train, and temperature and reveals a pulse height\u2010dependent spike rate in which devices exhibit excitatory spiking behavior under low input voltages and protective inhibition spiking under high voltages. Resistively coupled LIF neurons are shown to exhibit additional neural functionalities (i.e., phasic, regular and adaptation, etc.) depending on the input voltage and circuit parameters. The behavior of both individual and coupled neurons is shown to be described by a physics\u2010based lumped element circuit model, which therefore provides a solid foundation for exploring more complex systems. Finally, the performance of a perceptron SNN employing these LIF neurons is assessed by simulating the classification of image recognition algorithm. These results advance the development of robust solid\u2010state neurons with low power consumption for neuromorphic computing.\n
