Figure 1From: First spike latency sensitivity of spiking neuron modelsFirst spike latency in [4]when the Type A-current conductance is set to a value which corresponds to regenerative excitability. When the current is slightly above the saddle node, the neuron presents a robust first spike latency (A). First spike latency decreases with the relative variation of current ΔIr, i.e the distance to the saddle node bifurcation (B). Analytical predictions of a local model (solid line) fit the results obtained by numerical simulations of the full model (dots).Back to article page
