In contrast to flying flies, walking flies experience relatively strong rotational gaze shifts, even during overall straight phases of locomotion. These gaze shifts are caused by the walking apparatus and modulated by the stride frequency. Accordingly, even during straight walking phases, the retinal image flow is composed of both translational and rotational optic flow, which might affect spatial vision, as well as fixation behavior. We addressed this issue for an orientation task where… Expand
Impact of stride-coupled gaze shifts of walking blowflies on the neuronal representation of visual targets
As revealed by targeted modifications of the visual input during walking, the extraction of distance information on the basis of HSE responses is much impaired by stride-coupled retinal image shifts, and possible mechanisms that may cope with these stride-Coupled responses are discussed. Expand
Head orientation of walking blowflies is controlled by visual and mechanical cues
Both mechanical and visual cues contribute to gaze orientation during free walking in blowflies, and when visual cues are lacking, more weight is given to gravity. Expand
Saccadic movement strategy in a semiaquatic species – the harbour seal (Phoca vitulina)
ABSTRACT Moving animals can estimate the distance of visual objects from image shift on their retina (optic flow) created during translational, but not rotational movements. To facilitate thisExpand
How Lovebirds Maneuver Rapidly Using Super-Fast Head Saccades and Image Feature Stabilization
Observations show that rapidly maneuvering birds use precisely timed stereotypic gaze behaviors consisting of rapid head turns and frontal feature stabilization, which facilitates optical flow based flight control. Expand
Saccadic Movement Strategy in Common Cuttlefish (Sepia officinalis)
This study provides first evidence that an aquatic invertebrate, the cuttlefish, adopts a saccadic movement strategy depending on the behavioral context that could enhance the information gained from optic flow. Expand
Head roll stabilisation in the nocturnal bull ant Myrmecia pyriformis: implications for visual navigation
It is shown that nocturnal bull ants stabilise their head to varying degrees against locomotion-induced body roll movements, and this ability decreases as light levels fall, which has consequences for visual navigation. Expand
Strategies of locomotion composition.
This review aims to highlight the importance of saccades during locomotion as a strategy to reduce sensory information loss while the subject is moving to provide an elegant solution to optimise sensory flow. Expand
Saccadic body turns in walking Drosophila
The analysis shows that Drosophila does not turn its head relative to its body when turning during walking, which contrasts with the head saccades reported for e.g., blowflies and honeybees. Expand
A faithful internal representation of walking movements in the Drosophila visual system
A population of Drosophila neurons that were sensitive to visual flow patterns typically generated during locomotion, the horizontal system cells, encoded unambiguous quantitative information about the fly's walking behavior independently of vision, revealing a circuit for internally monitoring voluntary walking.

Local motion adaptation enhances the representation of spatial structure at EMD arrays
A novel adaptive model of the insect visual motion pathway could show that the motion detector responses to background structures of cluttered environments are largely attenuated as a consequence of motion adaptation, while responses to foreground objects stay constant or even increase. Expand


Saccadic head and thorax movements in freely walking blowflies
It is argued that the strategy of turning by saccades improves the performance of the visual system of blowflies. Expand
Visual control of locomotion in the walking fruitflyDrosophila
To investigate the optomotor leg responses of Drosophila melanogaster the free walking fly, the stimulus consists of continuous pattern movement in the equatorial zone of the visual field and leg responses show that the orientation of the movement detecting systems is independent of their position in the eye, and is invariant to the direction and velocity of the stimulus. Expand
Head and body stabilization in blowflies walking on differently structured substrates
No impairment in head and body stabilization during walks in darkness is found, which indicates that the control system mediating compensatory head movements works well without any visual input, and Interestingly, blowflies changed their walking style in the dark and seemed to use their forelegs as tactile probes. Expand
The halteres of the blowfly Calliphora
We quantitatively analysed compensatory head reactions of flies to imposed body rotations in yaw, pitch and roll and characterized the haltere as a sense organ for maintaining equilibrium. DuringExpand
Representation of behaviourally relevant information by blowfly motion-sensitive visual interneurons requires precise compensatory head movements
A `headifying algorithm', which transforms the time-dependent body orientation in free flight into an estimate of head orientation that is sufficiently stable to enable recovering information on translation, is introduced. Expand
Chasing Behavior and Optomotor Following in Free-Flying Male Blowflies: Flight Performance and Interactions of the Underlying Control Systems
Although blowflies are reluctant to fly at high background velocities, the performance and dynamical characteristics of the chasing system are not much affected when the background moves in either the same or in the opposite direction as the target. Expand
The fine structure of honeybee head and body yaw movements in a homing task
This work uses high-speed video equipment to record the head and body movements of honeybees approaching and departing from a food source that was located between three landmarks in an indoor flight arena to investigate how gaze and flight control interact in a homing task. Expand
Body movements and retinal pattern displacements while approaching a stationary object in the walking fly, Calliphora erythrocephala
The types of pattern projection into the visual field of the fly while approaching an object can be explained by a simple neuronal network characterized by either inhibitory and/or excitatory influences of the visually activated neurones on the motor neurones generating the propulsive forces, that means the forward motion. Expand
Gaze control in the blowfly Calliphora: a multisensory, two-stage integration process
Flies use several visual and mechanosensory cues to keep flight balance and to stabilize their eyes relative to the surroundings by compensatory head/eye movements. Expand
What causes edge fixation in walking flies?
F fixation behaviour in walking Lucilia females seems to be a simple taxis, if lateral inhibition creates a 'Mach-band' effect, making the edges of a dark region become more attractive than its centre. Expand
