Figure 7

Average A /P ( a) and M/ L (b) PSD magnitudes ( frequencies less than 0. 6 Hz) for the C2 (circles) and Tactaid ( squares) tactors during vibration as a function of tactor location. Error bars indicate standard error of the mean (***p < 0.0001). Bird’s-eye view drawings illustrate vibration locations. Note that the scale in (a) is ten times greater than that in (b).
