Effects of E-4031 (1 microM) and lindane (3.4 microM) on the action potential (AP). Superimposed traces of the AP recorded on frog auricle using intracellular microelectrodes. A. a): AP recorded before and after addition of E-4031 to the Ringer solution; b) further addition of lindane to the solution containing E-4031. B). AP recorded in the Ringer solution containing lindane before and after further addition of E-4031.
