Tuning functions of two example rFN neurons for which the conclusions regarding reference frame differed for vertical versus horizontal plane head reorientations. A, Example rFN cell exhibiting tuning better correlated with head-centered encoding of translation after vertical plane head reorientation (45° nose-down, DI = 0.76), but body-centered encoding of translation for horizontal plane reorientation (45° left, DI = 0.13; see Fig. 7A, diamonds). B, Example rFN cell exhibiting body-centered encoding of translation for vertical plane head reorientation (30° right-ear-down, DI = 0.19), but closer to head-centered tuning for horizontal plane reorientation (45° left, DI = 0.61; see Fig. 7A, triangles). Star: PD; pink circle: predicted PD for head-centered tuning; blue square: predicted PD for body-centered tuning.
