Fig. 3. The magnitude of the wingbeat responses to concurrent oscillations about
the pitch (A) and roll (B) axes is a function of the phase offset between
mechanical and visual stimuli. (A) Pitch axis responses (mean ±
S.E.M., N=10 flies). (B) Roll axis responses (mean
± S.E.M., N=14 flies). The amplitude of the sine
fits to wingbeat data (Rm+v; green circles) are plotted
against phase offset (
). In addition, two possible fits for the data are
plotted: linear summation (Rm+Rv;
black curve) and scaled summation
(
Rm+ßRv; red curve). The
two fitted functions are 4th order polynomials.
