The endocochlear potential is the sum of two potentials: a positive potential caused by active secretion of K+ by the stria vascularis (120mV) and a negative potential created by the passive diffusion of K+ ions from the hair cells (40mV), which can be visualised after an anoxia. install polishing filter reverse osmosis
