Summary of differences in direction tuning between SU and MU activity (passive fixation task). A and B: histograms of the absolute difference in 3D direction preferences (|∆Preferred direction|) between SU and MU tuning for vestibular (N = 142/425; red) and visual (N = 202/425; blue) translation (A) and for vestibular (N = 41) and visual (N = 29) rotation (B) conditions (shown only for pairs with significant tuning). C and D: distributions of the correlation coefficient (R_{SU, MU}) between SU and MU tuning curves (all neurons included) for vestibular and visual translation (C) and rotation (D) conditions. Solid and hatched bars indicate values of R_{SU, MU} that are significantly and nonsignificantly different from zero, respectively.
