DC potentials of the lateral wall of the scala media.
We recorded DC potential and resistance changes of the cochlear lateral wall in guinea pigs, using (3M KCl) electrolyte glass microelectrodes. The patterns found for slow penetration showed different potential and resistance characteristics at different segments of the lateral wall. In addition, our findings demonstrate that the monitoring of microelectrode tip resistance is a useful procedure for DC cochlear recordings.
