From: Ramped pulse shapes are more efficient for cochlear implant stimulation in an animal model
rampDOWN have shorter wave II latency than Rec. (a) Individual wave II latencies as a function of charge. Mouse (M)1–12. Pulse shapes are indicated by color and shown in the legend (bottom right). Solid line, anodic-first; dashed, cathodic-first. Note the longer latency with M7 and M9. (b) Wave II latency at three dB above threshold. (c) Wave II latency at three dB above threshold with M7 and M9 excluded. Pulse shapes are drawn on the x-axis. Each circle is data from one mouse. Closed circles, anodic-first pulses; open circles, cathodic-first pulses. Asterisk and diamond denote significant effect in post-hoc test of the factor pulse shape and the pulse shape*polarity interaction (Tukey HSD), respectively. *p ≤ 0.05; ♦p ≤ 0.05. n = 12. Error bars are SEM.
