Examination of fly motion vision by functional fluorescence techniques

Examination of fly motion vision by functional fluorescence techniques.

Over the past years, classical electrophysiological approaches to elucidate the functioning of nerve cells have been complemented by functional optical methods, in particular fluorescence imaging. This review illustrates how optical methods have proved helpful in the analysis of the neuronal principles underlying visual motion processing in the fly, a model system which allows physiological inv...

Modelling Fly Motion Vision

Afterimages in fly motion vision

Afterimage-like effects modulate the responses of fly wide-field motion-sensitive cells following adaptation to stationary or slowly moving patterns. The origin of these afterimages is unclear. They have been interpreted as either the result of adaptation in the early visual system or as a direct consequence of the correlation scheme of motion detection. Using a combination of intracellular rec...

Dependency Coefficient in Computerized GALS Examination Utilizing Motion Analysis Techniques

Objectives: The GALS (Gait, Arms, Legs and Spine) examination is a compact version of standard procedures used by rheumatologists to determine musculoskeletal disorders in patients. Computerization of such a clinical procedure is necessary to ensure an objective evaluation. This article presents the first steps in such an approach by outlining a procedure to use motion analysis techniques as a ...

Fly Vision: Neural Mechanisms of Motion Computation

A wide range of novel approaches are being used to dissect the visual system of the fly, both the neural networks of motion detection and the performance of these networks under complex natural stimulus conditions.
