Figure 3.
Psychometric function slopes were shallower and performance was more variable for animals with CHL. Each animal's FM psychometric function slope, d′/log10(Hz), is plotted against the FM detection threshold. The psychometric function slopes were steepest for control animals. Furthermore, there was a significant correlation between threshold and slope for all animals. Values were obtained from the psychometric functions with the three best FM depth threshold values, as described in Figure 2B. Error bars indicate ± SEM.
