Optimizing stimulation parameters to record electrically evoked cortical auditory potentials in cochlear implant users.

To measure the effect of burst duration, stimulated electrode position, and stimulation level on the P1-N1-P2 electrically evoked cortical auditory potentials (eCAEPs) elicited via the direct stimulation of selected electrode contacts on a cochlear implant (CI) electrode array. Prospective observational study of 20 adult cochlear implant users with a MED-EL CI system. eCAEPs were recorded simultaneously with the (Interacoustics) and the (Nihon Kohden) recording systems.
