Figure 6.

Dependence of tuning function parameters on head orientation. Tuning parameters after head reorientation in the vertical (circles) and horizontal (squares) planes are plotted versus the corresponding values with the head upright and straight forward relative to the body. A, Gain along the maximum response direction. B, Phase along the maximum response direction. C, STC ratio. Filled symbols denote parameter values that were significantly different after head reorientation compared with upright. Red denotes rFN cells. Blue denotes VN cells. Dashed line indicates unity slope.
