Abstract

1. 1. Intracellular injection of 2,4-DNP decreased the amplitude and frequency of the slow oscillation of membrane potential but did not eliminate spike generation. 2. 2. During lengthened interburst intervals fast oscillation with low amplitude occurred. 3. 3. Intracellularly injected CdCl2 increased the amplitude of the slow oscillation after a transient depolarization then paroxismal activity appeared. 4. 4. Speed of the inward current decreased significantly after 2,4-DNP injection while it was not influenced by CdCl2. The amplitude of the inward current was decreased in both cases. 5. 5. The initial value of the outward current was decreased strongly at 2,4-DNP injection while its steady state value at CdCl2 injection.
