Figure 10.

Comparison between response gain during tilt and translation as a function of frequency. Gain has been expressed relative to linear acceleration. Data are shown from two different experiments: those matching translation and tilt (0.16–1 Hz; cyan and magenta dashed lines, respectively) and those testing translation or tilt separately (solid blue and red lines, respectively). The black solid line illustrates the vectorial difference between translation (otolith-driven response) and tilt-translation (canal-driven response) gains (computed from the 0.16–1 Hz data only). The solid and dashed gray lines illustrate the mean gains from regular and irregular otolith afferents [replotted from the study by Fernández and Goldberg (1976)].
