Figure 3: Phase vs stimulus frequency for basal and apical TMs.
From: Tectorial membrane travelling waves underlie abnormal hearing in Tectb mutant mice
(a) Basal Tectb−/− TM segments (n=3 TM preparations; red open circles) accumulated more phase (>10 kHz) than did basal wild-type TMs (n=3 TM preparations; blue closed circles) at a location ∼250 μm from the vibrating support. (b) Phase accumulation was greater for apical Tectb−/− TMs (n=4 TM preparations; red open circles) compared with apical wild-type TMs (n=3 TM preparations; blue closed circles) at frequencies above 1 kHz (at ∼250 μm location). Lines are linear regression fits to the data. The grey shaded region denotes the range of frequencies (>11 kHz) when TM motion was too small to measure phase differences.
