“…4 Ai,Ciii). If stroke amplitude is correlated with yaw torque as has been documented in several previous studies (Götz et al, 1979;Tammero et al, 2004), the above two effects would both decrease the compensatory torque response to a rotational visual stimulus, suggesting that the mechanosensory feedback mediated by JO afferents normally increases the strength of optomotor responses to rotational visual motion.…”

Insects use feedback from a variety of sensory modalities, including mechanoreceptors on their antennae, to stabilize the direction and speed of flight. Like all arthropod appendages, antennae not only supply sensory information but may also be actively positioned by control muscles. However, how flying insects move their antennae during active turns and how such movements might influence steering responses are currently unknown. Here we examined the antennal movements of flying Drosophila during visually induced turns in a tethered flight arena. In response to both rotational and translational patterns of visual motion, Drosophila actively moved their antennae in a direction opposite to that of the visual motion. We also observed two types of passive antennal movements: small tonic deflections of the antenna and rapid oscillations at wing beat frequency. These passive movements are likely the result of wing-induced airflow and increased in magnitude when the angular distance between the wing and the antenna decreased. In response to rotational visual motion, increases in passive antennal movements appear to trigger a reflex that reduces the stroke amplitude of the contralateral wing, thereby enhancing the visually induced turn. Although the active antennal movements significantly increased antennal oscillation by bringing the arista closer to the wings, it did not significantly affect the turning response in our head-fixed, tethered flies. These results are consistent with the hypothesis that flying Drosophila use mechanosensory feedback to detect changes in the wing induced airflow during visually induced turns and that this feedback plays a role in regulating the magnitude of steering responses.

“…As in other studies, the final motor output mediated by the different steering muscles was simply correlated with their spike activity. The complicated transformation of muscle activity into the different wing beat parameters and eventually the flight torques (G6tz et al 1979;Zanker 1987) was not taken into account.…”

Summary. In tethered flying house-flies (Musca domestica) visually induced turning reactions weremonitored under open-loop conditions simultaneously with the spike activity of four types of steering muscles (M.bl, M.b2, M.II, M.III1). Specific behavioral response components are attributed to the activity of particular muscles. Compensatory optomotor turning reactions to large-field image displacements mainly occur when the stimulus pattern oscillates at low frequencies. In contrast, turning responses towards objects are preferentially induced by motion of relatively small stimuli at high oscillation frequencies. The different steering muscles seem to be functionally specialized in that they contribute to the control of these behavioral responses in different ways. The muscles I1, IIIl and b2 are preferentially active during small-field motion at high oscillation frequencies. They are much less active during small-field motion at low oscillation frequencies and large-field motion at all oscillation frequencies which were tested. M.b2 is most extreme in this respect. These steering muscles thus mediate :mainly turns towards objects. In contrast, M.bl responds best during large-field motion at low oscillation frequencies and, thus, is appropriate to control compensatory optomotor responses. However, the activity of this muscle is also strongly modulated during small-field motion at high oscillation frequencies and, therefore, may be involved also in the control of turns towards objects. These functional specializations of the different steering muscles in mediating different behavioral ~response components are related to the properties of two parallel visual pathways that are selectively tuned to largefield and small-field motion, respectively.Abbreviations.

“…(Figure 3a) is mediated through the compound eyes and requires a nonlinear interaction between two adjacent inputs. 41,42 T he spatial arrangement of the two inputs determines the directional specificity of the local movement signal. To perceive motion in arbitrary directions at one point in the visual field, there are thought to be a set of probably six unidirectional movement detectors for each element of visual space.…”
