EAP signals obtained from a human subject. EAP signals recorded with different stimulation currents from a human subject implanted with the MED-EL PULSARCI¹⁰⁰ cochlear implant [17]. The EAP is detectable for stimulation currents above a certain threshold level, and the EAP amplitude increases with higher stimulation. The stimulation current values are indicated next to the corresponding EAP recordings. Signals are plotted at different offsets to clearly distinguish them. The zero-point of the time axis corresponds to the starting point of the recording.
