Shown are the 95th percentile (pctl) and median values of velocity, displacement (Disp.), and angular displacement (Ang. disp.) in response to 10 Hz–10 kHz sinusoidal electrical chirps at 400 Vpp amplitude. Results are from both charged and uncharged preparations. Asterisks show significance of difference between hair and antennae response under identical preparation and stimulation [t test (paired): **P ≤ 0.01; ***P ≤ 0.001; n = 10]. n.s., not significant.
