Cathodic pulses evoke larger inferior colliculus responses than anodic pulses
Evidence
Figure 2c shows the response amplitude as a function of current level for the same subject and the same pulse shape. It can be seen that at all current levels, the response was larger for the cathodic (RPS-IPG-C) than for the anodic (RPS-IPG-A) pulse. As depicted in the next section, this trend was observed in most of our subjects. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2272
