Fig. 8. Close-up of the flight sequence in a stationary arena cylinder (left turn).
(A) The fly's gaze calculated from body orientation. (B) Inverse relationship
between horizontal (blue, right scale) and turning (red, right scale)
velocity, and output of a rotation-sensitive EMD system (left-minus-right eye,
black, left scale).The sum of EMD responses of the two eyes is plotted in grey
(left scale). Light grey area indicates times at which the fly exhibits
approximately constant gaze in A and saccades in B.
