Synaptic and intrinsic currents in a PN from the simulation results shown in Fig 1.

<p>Left panel: the slow components of the repolarizing currents (black lines) and depolarizing currents (magenta lines); <i>I</i>_SK and-<i>I</i>_nACh (A), <i>I</i>_A and—<i>I</i>_Na (C) and <i>I</i>_Kd and—<i>I</i>_Ca (E). Right panel: Fast components of the repolarizing (black lines) and depolarizing currents (magenta lines); <i>I</i>_SK and <i>I</i>_nACh (B), <i>I</i>_A and <i>I</i>_Na (D) and <i>I</i>_Kd and <i>I</i>_Ca (F). Note that in the left panel we draw the minus values of <i>I</i>_nACh, <i>I</i>_Na, <i>I</i>_Ca for comparing their amplitudes, while in the right panel we draw the values of <i>I</i>_nACh, <i>I</i>_Na, <i>I</i>_Ca directly for comparing their depolarizing and repolarizing effects). The slow components of E₁ (from 5140 to 5770ms) and I (from 5770 to 6700ms) are enlarged in the insets in A, C and E; and the fast components of E₁ and the period transiting from E₁ to I (from 5770 to 6200ms) are enlarged in the insets in B, D and F.
