Fig. 6. Coherence of sideward angular velocity (solid line) and yaw velocity (broken line) with the subtracted responses of right and left horizontal system equatorial neuron (HSE) (A–C), horizontal system south neuron (HSS) (D–F) and dorsal centrifugal horizontal neuron (DCH) cell (G–I), intersaccadic parts of stimulus and response only. Responses to optic flow based on head (A,D,G), body (B,E,H) or yaw tuned body (C,F,I) movements. Single cell results, based on 3–8 stimulus repetitions of two different flights. Sideward is perpendicular to the head's plane of symmetry.
