Abstract
Intracellular recordings were made from inner hair cells, outer hair cells and supporting cells in the fook area of the guinea-pig cochlea, the recording sites being confirmed by the injection of Alucion blue dye and subsequent surface prepalation technic. Inner hair cells had resting potentials between 57 and 92mV, outer hair cells had between 75 and 88mV. Both hair cells were recorded DC potentials about 0.6mV in amplitude in response to a tone burst of 10 KHz of ca. 30dB up the CM threthold. The AC response was recorded maximary at the inner hair cells in response to a 10KHz tone burst, but at the outer cells the AC response was small. Those conclusion were thinking out that inner hair cells earring a principal dutis in transduction at the Organ of Corti.
