Fig. 5From: Stochastic Hybrid Systems in Cellular NeuroscienceSketch of deterministic potential \(\varPsi(v)\) as a function of voltage v for different values of the applied stimulus current \(I_{\mathrm{app}}\). At a critical current \(I_{*}\), the deterministic system switches from a bistable to a monostable regime, that is, \(I^{*}\) is the threshold current for action potential generationBack to article page
