Neural circuits in the cockpit of the fly — •Alexander Borst — MPI of Neurobiology, Am Klopferspitz 18 a, 82152 Martinsried

Flies are known to be masters in aerobatics. Their fantastic maneuverability in the air is due to two interacting control systems: the mechanosensory and the visual system. Because the images of the environment permanently move across the eyes when the animal is moving, and because the spatial distribution of visual motion, the so-called flow-field, depends on the exact maneuver of the fly, visual motion represents a prime sensory cue in flight control. I will present the current state of knowledge about the neural processing of visual motion in the fly brain, ranging from the biophysical membrane properties of single neurons through network interactions up to the integration of visual motion information with mechanosensory input eventually leading to output signals to the flight motor.
