Fig. 3
Spatial response profiles showing response in the inferior colliculus to virtual channel stimuli. Successive panels show IC response rate (color) to increasingly larger total applied cathodic current. Variation along abscissa corresponds to variation of virtual channel stimulus. Diagonal trajectory of response peaks (asterisks) for currents above 0.060 mA indicates that response was evoked in regions of IC neurons that were between those evoked by single-channel stimulation (see text for details). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
