Intracellular potentials of the organ of Corti in guinea pigs.

2 Introduction Cochlear microphonic potentials (CM) can be recroded from the intact organ of Corti, but it is still an open question whether they are essential phenomena in the sound reception of hair cells. In order to determine what motivates the release of chemical transmitters at the synaptic end of hair cells, potentials in response to sound stimulations have to be intracellularly recorded. The intracellular potentials are identified by means of a marking technique using Alcian Blue dye.
