Figure 3From: Inactivation properties of sodium channel Nav1.8 maintain action potential amplitude in small DRG neurons in the context of depolarizationPotassium channel blockers reduce outward currents. Voltage clamped currents in response to depolarizing voltage steps from a holding potential of -100 mV are shown for two separate small DRG neurons. Cells were recorded in the absence (top) and presence (bottom) of the potassium channel blockers TEA and 4-AP.Back to article page
