Figure 7.
KCNQ3 channels are required for retigabine to modulate the IsAHP time course. (a) Left: superimposed normalized IsAHP traces before (black) and after (red) application of 40 μM retigabine in control pyramidal neurons. Right: summary data showing the effect of retigabine on the activation and decay time constants in control neurons (n = 7, ∗p < 0.05, Student’s t-test). (b) Left: superimposed normalized IsAHP traces before (black) and after (red) application of 40 μM retigabine in Kcnq3-null pyramidal neurons. Right: summary data showing the effect of retigabine on the activation and decay time constants in Kcnq3-null neurons (n = 7, ∗p < 0.05, Student’s t-test). To see this figure in color, go online.
