Abstract :
Changes in the applied current level to a cochlear implant when using high pulse rate electric stimuli produce discernable changes in unit population responses. More than 37% of units with only one pattern of response to electric stimulation respond to suprathreshold increases in current level with monotonic increases in spike rate for pulse rates from 125 to 4000 pulses per second (pps). These findings support the use of high pulse rate stimuli in cochlear implant systems
