It has been concluded in the preceding papers (Egelhaaf, 1985a, b) that two functional classes of output elements of the visual ganglia might be involved in figure-ground discrimination by relative motion in the fly: The Horizontal Cells which respond best to the motion of large textured patterns and the FD-cells which are most sensitive to small moving objects. In this paper it is studied by computer simulations (1) in what way the input circuitry of the FD-cells might be organized and (2) the… 
Processing of figure and background motion in the visual system of the fly
TLDR
Computer simulations of the postulated mechanisms of the SF-and LF-system reveal that these can account for the specific features of the behavioral responses under quite different conditions of coherent large-field motion and relative motion of different pattern segments.
Detection of object motion by a fly neuron during simulated flight
Abstract Object detection on the basis of relative motion was investigated in the fly at the neuronal level. A representative of the figure detection cells (FD-cells), the FD1b-cell, was
Neural circuit tuning fly visual interneurons to motion of small objects. I. Dissection of the circuit by pharmacological and photoinactivation techniques.
TLDR
The tuning of the FD1-cell to small moving objects relies on a GABAergic mechanism and, thus, most likely on the CH-cells, and the important role of the VCH-cells in mediating the characteristic sensitivity of theFD1- cell to motion of small objects is revealed.
Neuronal encoding of object and distance information: a model simulation study on naturalistic optic flow processing
TLDR
A model of the input circuitry of the FD1 cell, an identified motion-sensitive interneuron in the blowfly's visual system, successfully reproduces theFD1 cell's most conspicuous property: its larger responses to objects than to spatially extended patterns.
Object representation and distance encoding in three-dimensional environments by a neural circuit in the visual system of the blowfly.
TLDR
Three motion-sensitive key elements of a neural circuit, presumably involved in processing object and distance information, were analyzed with optic flow sequences as experienced by blowflies in a three-dimensional environment, showing strong dependence of FD1 on background distance and VCH on inhibitory strength with increasing distance.

TLDR
The visually guided flight maneuvers of the fly have turned out to be one of the few cases in which it has been feasible to reach an understanding of the mechanisms underlying a complex behavioral performance at successively reductive levels of analysis.
MINI MOTION COMPUTATION IN REVIEW AND VISUAL ORIENTATION FLIES
TLDR
In a combination of behavioral, neurophysiological and pharmacological analysis and modelling, the mechanisms are established by which the visual system of the fly extracts three types of-basic retinal motion patterns: coherent retinal large-field motion as is induced during deviations of the animal from its course, image expansion occurring when the animal approaches an obstacle, and relative motion which is induced when a nearby object is passed in front of its background.

TLDR
The phenomenological theory outlines the basic logical organization of the visual control system of the fly and describes the neural network between the receptors and the flight muscles to perform two main computations on the visual input.
Single visual neurons code opposing motion independent of direction.
TLDR
Cells in intermediate and deeper layers of the pigeon optic tectum respond best when a textured background pattern is moved in the opposite direction to a moving test spot, indicating a higher level of abstraction in a motion-detecting system.

TLDR
Empirical studies show the predictions of this computation of an instantaneous two-dimensional velocity field from the changing image to be consistent with human motion perception, and an additional constraint of smoothness of the velocity field is formulated, based on the physical assumption that surfaces are generally smooth.

TLDR
There is strong evidence that the lobula plate is the main motion computation centre of the optic lobe controlling the optomotor responses of the fly.
Fundamental Properties of Intensity, Form, and Motion Perception in the Visual Nervous Systems of Calliphora phaenicia and Musca domestica
TLDR
It is shown that the response of both form and motion detection units is independent of the direction of pattern intensity gradation, and that failure to detect motion properly must start at a spatial wavelength four times the effective sampling station spacing rather than twice as has been predicted previously.
Visual orientation behaviour of flies after selective laser beam ablation of interneurones
TLDR
It is suggested that other sets of nerve cells are involved in the information processing of single moving objects, whereas the horizontal and vertical cells seem to be implicated in ordinary optomotor flight stabilization.
Functional Neuroanatomy of the Blowfly’s Visual System
TLDR
Outputs from the optic lobes arise mainly in the lobula (Lo) and lobula plate (LP), two neuropils each with distinct architectures, which are thought to be involved in visual stabilization of flight.
