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...

Fly neurobiology: development and function of the brain. Meeting on the Neurobiology of Drosophila.

Introduction Studies of the tiny fruit fly, Drosophila melanogaster, have heralded remarkable discoveries ranging from the genetic basis of heredity to the development of the animal body plan. an outstanding mystery that drives neuroscience research today is how the brain encodes cognition and behaviour. the beautifully organized brain architecture, the relatively small number of neurons, and t...

Behavioral Neurobiology: A Vibrating Gyroscope Controls Fly Steering Maneuvers

A clever 'virtual reality' experiment reveals that specialized mechanosensory organs, rather than the eyes, orchestrate the high-performance staccato turns that characterize the flight behavior of a fly.
