Abstrakt:	Summary The effects of restoring serosal potassium to potassium-depleted toad urinary bladders have been, re-examined using double-barrelled microelectrodes. The data confirm the existence of a time-lag phenomenon, a dissociation between potassium reaccumulation and restoration of short-circuit current. Returning serosal potassium stimulates an increase in intracellular potassium activity 21–26 min before any increase can be detected in short-circuit current.
