FIG. 5.
Postmortem BM signal-front and BF group delays in the cochleae of humans and other mammals. Delays are expressed in milliseconds. Dashed lines, in vivo signal-front delays in chinchilla. Solid lines, the trend of postmortem BF group delays in all species. Signal-front delays in the cochleae of human cadavers from Figure 11 of von Békésy (1949a). Best frequency group delays in the cochleae of human cadavers: from Figures 4 and 5 of von Békésy (1947), Figure 5B of Stenfelt et al. (2003), and Figure 3 of Gundersen et al. (1978). Postmortem delays in chinchilla: Figure 1 of Ruggero et al. (2000), Figure 10 of Recio et al. (1998), Figure 7 of Cooper and Rhode (1996), Figures 1A and 2D of Rhode and Recio (2000), and Figure 4 of Ruggero et al. (1992). Guinea pig: from Figure 6 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). Squirrel monkey: from Figures 2, 3, and 4 of Rhode (1973).
