Fig. 4.

Left and right-hand columns show the standard and signal intervals of a 2IFC trial for various tasks that have been shown to vary substantially across electrodes. Solid lines in part a) illustrates the measurement of modulation detection thresholds (MDTs) in quiet; the dashed lines illustrate unmodulated pulse trains presented to an adjacent channel for the measurement of masked MDTs (Garadat et al. 2012). Other tasks are b) electrode discrimination, c) detection thresholds, d) gap detection, and e) rate discrimination
