Potassium concentration in the inner sulcus is perilymph-like.
Using potassium-selective microelectrodes and an improved observation technique, it is shown that the potassium concentration in the fluid of the inner sulcus of the guinea pig is like that of perilymph. The implications for the common concepts about the role of potassium in the cochlea are discussed.
