Threshold functions for electrical stimulation of the human cochlear nucleus.
Thresholds to sinusoidal and biphasic pulsatile electrical stimuli were measured in two patients with electrodes positioned on the cochlear nucleus. The threshold functions differ from those observed in patients with scala tympani electrodes, primarily at low sinusoidal frequencies and long pulse widths. This difference is probably due to differences in the biophysical properties of the stimulated neural tissues in the two regions.
