Voltage-clamp experiments have been performed in order to investigate the after effects of Na-accumulation in myelinated nerve fibres from the frogRana esculenta. 1. The ionic current associated with a depolarizing test-pulse adjusted to the sodium equilibrium potential has been measured following conditioning volleys of depolarizing pulses. 2. A marked shift ofE Na towards less positive potentials has been observed following volleys of more than 50 msec; the time course of recovery ofE Na… CONTINUE READING
