SK_Ca with IR: Role of SK_Ca inward rectification and SK_Ca and maximum conductance on inflammatory repetitive firing.

<p>Membrane potential, V_m (upper panel), intracellular calcium concentration, [Ca]_i (middle panel) and instantaneous SK_Ca conductance, <i>g</i> (lower panel) recorded against time for three maximum conductances () of the SK_Ca channel: 9*10⁻⁴ S/cm² (control) (A, D, G), 2.7*10⁻³ S/cm² (B, E, H) and 4.5*10⁻³ S/cm² (C, F, I). The neuron model used had SK_Ca channels endowed with inward rectification (SK_Ca with IR). Stimulus: 1000 ms, 0.12 nA rectangular current clamp.
