Abstract
Tntracellular membrane potentials and resistance measurements were made from cells in the lateral line organs of the burbot (Lota Zota). The membrane potentials varied from 10-65 mV and the resistances from 8-110 Mω. A relationship exists between the membrane potential and resistance. Under resting conditions there is no detectable difference in the membrane potential and resistance between hair cells and supporting cells. Hair cells are electrically inexcitable, and the specific resistance of the hair cell membrane is 100-1000 ω/cm2 and its capacitance is < 0.3 μF/cm2.
