Fig. 5. Modifying haltere feedback changes saccade dynamics. (A) The halteres. (B)
Angular rotations of the fly's body cause the halteres to be deflected out of
their stroke plane by Coriolis forces. In our preparation, these forces are
proportional to the fly's angular velocity about its yaw axis (
) and
the halteres' mass (m) and velocity (v). The deflections
caused by the Coriolis forces are sensed by haltere mechanoreceptors. (C)
Changing the amount of haltere feedback affects saccade dynamics. Top to
bottom: control (same data as top row of
Fig. 3, N=14 flies,
n=134 saccades); haltere feedback increased by adding mass to the
haltere endknobs (N=6, n=113); haltere feedback decreased by
ablating left haltere (N=5, n=121). Statistical analysis was
as in Fig. 3
(*P<0.001).
