FIG. 6.

In-vivo CFs and CF group delays for low-level stimuli in mammalian cochleae expressed as ratios of postmortem BFs and postmortem CF group delays. A In vivo CFs expressed relative to the BFs of responses to intense stimuli postmortem (plain symbols) or in vivo (dotted symbols). B The relationship between in vivo CF BM group delay for low-level stimuli and postmortem CF group delay in experimental animals. Solid line, trend between in vivo CF group delay for responses to low-level stimuli and postmortem CF group delay. Dashed line, equality between in vivo CF group delay for low-level stimulation and postmortem CF group delay. Chinchilla: from Figures 11A and B of Rhode and Cooper (1996), Figure 5 of Cooper and Rhode (1996), Figure 9 of Ruggero et al. (1997), Figure 1 of Ruggero et al. (2000), Figures 1C, 2B, 3B, and E of Rhode and Recio (2000), Figure 10 of Recio et al. (1998), and Figures 2 and 4 of Ruggero et al. (1992). Guinea pig: from Figure 6 and Table I of Zinn et al. (2000) and Figure 6 of Nuttall and Dolan (1996). Gerbil: from Figure 3 of Ren and Nuttall (2001) and Figures 4 and 5 of Overstreet et al. (2002a).
