Fig. 4. Angular ranges and central positions for the horizontal and vertical
components in both antennae and head. Bars and symbols indicate the mean
angular ranges and central positions, respectively (N=10). Working
ranges for antennal horizontal and head yaw components decreased,
respectively, by about 2530° and 15° during walking, but were
not largely changed for antennal vertical and head pitch component s. Vertical
central positions for both antennae were lowered by 1525° during
walking. R, right; L, left.
