Figure 4From: Activation of ATP-sensitive potassium channels antagonize nociceptive behavior and hyperexcitability of DRG neurons from rats K ATP opener activates glyburide-sensitive currents in DRG neurons. (A) Representative current traces recorded from a small diameter DRG neuron using the voltage protocol shown at the top. Perforated whole-cell patch clamp was used. Effects of pinacidil (Pin) and pinacidil (Pin) plus glyburide (Gly) were indicated. (B) The time course of currents recorded at -20 mV and -140 mV from a small diameter neuron. Effects of KATP openers and blocker were indicated.Back to article page
