Measurements of threshold shifts observed when using normal and preformed electrodes.
OBJECTIVE
To investigate the efficacy of short-term electrical stimulation with different human electrodes using high stimulation rates and different electrode designs.


METHODS
Human electrodes of two different designs were implanted in cats, and electrically evoked auditory brain stem responses (EABR) were recorded.


CONCLUSIONS
Thresholds from the EABR recordings at the apical end of the electrode array were comparable in both types of implants. There were significantly higher thresholds at the basal end than at the apical end of the electrodes in both types of electrodes.
