Peripheral neural responses to cochlear stimulation via electrically evoked compound action potentials (ECAPs) of differing pulse distance and interphase gap

These data contain minimum and maximum Current Levels (CLs) that evoke ECAPs within the recoverable ECAP dynamic range for 52 electrodes of 10 cochlear implant users.

Data were collected with stimulus Interphase Gap (IPG) settings of 8 and 25 µS, and Pulse Distance (PD) settings of 25 and 40 µS, for each electrode.

These data are paired with four-interval-forced-choice behavioural thresholds for stimuli delivered at 40, 500, 1000, and 2000 pps (pulses per second), with IPG 8 and PD 25 µS.

These data were collected for the purpose of determining whether there is a correlation between the effect of changing PD/IPG on ECAP amplitude, and the slope of behavioural thresholds across pps conditions.
