Principles of visual motion detection
We show that the mechanisms underlying biological motion detection can be attributed to only a few, essentially equivalent computational principles. Expand

Computational structure of a biological motion-detection system as revealed by local detector analysis in the fly's nervous system.
The computations performed by individual movement detectors are analyzed by intracellularly recording from an identified direction-selective motion-sensitive interneuron in the fly's brain and byExpand

Transient and steady-state response properties of movement detectors.
The transient and steady-state responses of movement detectors are studied at various pattern contrasts (i) by intracellularly recording from an identified movement-sensitive interneuron in the fly'sExpand

Binocular contributions to optic flow processing in the fly visual system.
Integrating binocular motion information tunes wide-field direction-selective neurons in the fly optic lobe to respond preferentially to specific optic flow fields. This is shown by measuring theExpand

Neural Mechanisms of Visual Course Control in Insects
Visual orientation and course-stabilization of flying insects rely essentially on the evaluation of the retinal motion patterns perceived by the animals during flight. Expand

Mechanisms of dendritic integration underlying gain control in fly motion-sensitive interneurons
In the compensatory optomotor response of the fly the interesting phenomenon of gain control has been observed by Reichardt and colleagues (Reichardt et al., 1983): The amplitude of the responseExpand

  • 1 June 1985
A new class of large-field tangential neurones (Figure Detection (FD-) cells) has been found and analysed in the lobula plate, the posterior part of the third visual ganglion, of the fly by combined extra-and intracellular recording as well as Lucifer Yellow injection. Expand

Speed tuning in elementary motion detectors of the correlation type
We show that other versions of the correlation model, which consists of a single unidirectional motion detector with opposite preferred directions, produces a response which varies not only with the velocity of the image, but also with its spatial structure and contrast. Expand

On the neuronal basis of figure-ground discrimination by relative motion in the visual system of the fly
A fly can discriminate an object (“figure”) from its background on the basis of motion information alone. This information processing task has been analysed, so far, mainly in behavioural studies butExpand

Chasing a dummy target: smooth pursuit and velocity control in male blowflies
Male blowflies chase and catch other flies in fast acrobatic flights. To unravel the underlying control system, we presented a black moving sphere instead of a real fly as a pursuit target. ByExpand
