Operating ranges for cochlear implants.
The range of simple electrical stimuli that may be used for prosthetic stimulation via scala tympani implants was explored using psychophysical procedures in macaque monkeys. Biophysical considerations placed further limitations on the operating range. The operating range was dependent onstimulus waveform, electrode configuration, and the condition of the implanted cochlea and eighth nerve.
