Steady-state approximations for Hodgkin-Huxley cell models: Reduction of order for uterine smooth muscle cell model

Fig 7

RTM: Variation of Iapp.

Comparison results from Tong, 2011 Fig 11A, Fig 11B and Fig 11C and Tong, 2014 Fig 8D. Stimulus strength varied as noted aimed at reproducing experimental results (insets, Panels A-C) as given in Tong, 2011 Fig 11, or extended bursting (Panel D). Each Iapp applied up to t = 10 s starting at t = 1 s, except Panel D out to t = 50 s. Additional simulation with elevated extracellular initial condition K+ at 10 mM for comparison and no applied stimulus (blue dotted, Panel B). Conductances for key currents: gCaL = 0.6, gNa = 0.0895, gK1 = 0.7 pA/pF (identical to SSP values, Panels A-C), with gK1 = 0.75 for Panel D. Experimental traces (insets) adapted from Tong, et al. 2011 Fig 11.
