Spiking neuron model (Eshraghian et al., 2021). (A) Intracellular and extracellular mediums are divided by an isolating bilipid membrane. Gated ion channels allow ions such as Na+ to diffuse through the membrane. (B) Capacitive membrane and resistive ion channels constitute a resistor-capacitance circuit. A spike is generated when the membrane potential exceeds a threshold Vth. (C) Via the dendritic tree, input spikes generated by I are transmitted to the neuron body. Sufficient excitation will cause output spike emission. (D) Simulation depicting the membrane potential V(t) reaching Vth, resulting in output spikes.
