Fig. 6

The graph of derivative and phase planes of (5) with 3 sets of parameters. A: The time derivative of voltage is always positive and the cell without M-current has a natural frequency of 34 Hz (\(g_{M}=0\) mS/cm2, \(I_{\mathit {app}}=0.68\) μA/cm2, \(a=0\)). B: The phase plane of the cell with M-current. The cell is firing at 34 Hz without external inputs (\(g_{M}=1.5\) mS/cm2, \(I_{\mathit {app}}=9.1\) μA/cm2, \(a=0\)). C: The same cell as in B but with 32 Hz external pulses. The voltage resets to a higher point near the V-nullcline than in B (\(g_{M}=1.5\) mS/cm2, \(I_{\mathit {app}}=9.1\) μA/cm2, \(a=0.6\))
