FIG. 3.

Cupula displacement and afferent time constants in normal animals. Simultaneous recordings of afferent responses (A, D, G) and cupulae deflections (B, E, H) in response to square wave mechanical indentation (C, F, I) of the canal duct for three different animals. Cupula deflections in the central ROI were 3–6 μm for duct indentations of 20 μm, and cupula time constants for the units in this figure were τ = 13–54 s. Afferent response time constants were less than cupula time constants due to adaptive processes in the hair cell/afferent complex.
