Figure 5.
Comparison of estimates of preferred directions to tangential force component applied at different vertical angles for 16 SA-IInail afferents. A, B, Scatter plots showing the relationship between the preferred directions estimated with stimulation forces applied at 30° versus 20° vertical angles (raa = 0.96, p < 0.001), and at 30° versus 10° vertical angles (raa = 0.48, p < 0.01), respectively. Two outliers are coded by open circles in B. The dotted line is a unity line showing equivalent preferred direction on the ordinate and abscissa. Polar coordinate as in Figures 1B and 4A.
