Effect of ionic conductances on the response of the PG cell model.

<p>The graphs show the membrane potential of the PG cell model in response to a depolarizing current of 100 pA injected at the soma for 600 ms starting at 200 ms. The maximum conductance densities (in S/cm²) are indicated in each graph. (A) Effect of varying the maximum conductance density of the hiperpolarization-activated current (). A zoom of the region indicated by dots is shown at the inset. (B) Effect of varying the maximum conductance density of the sodium current (). The inset shows the latency (L) of the spike peak measured from stimulus onset as a function of . (C) Effect of varying the maximum conductance density of the rectifier potassium current (). (D) Effect of varying the maximum conductance density of the A-type inactivating potassium current (). (E) Effect of varying the maximum conductance density of the T-type calcium current (). (F) Effect of values of the current higher than S/cm. The graph shows the behavior of the membrane potential for two values of ( S/cm and S/cm). (G) Effect of varying the maximum conductance of the self-inhibitory synapse on the membrane potential of the PG cell model. (H) Response of the PG cell model with the parameters of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0056148#pone-0056148-t001" target="_blank">table 1</a>.
