Adaptive encoding of motion information in the fly visual system

摘要: Adaptation is a ubiquitous mechanism by which sensory cells and neurons match their response properties to the currently prevailing features of input stimuli. Visual motion-sensitive in fly brain have been used as valuable model system for vivo analysis physiological mechanisms underlying neuronal adaptation. In this functional significance adaptation visual control flight movements can be evaluated. Although effects on sensitivity principle understood modifications input-output functions, exact nature these changes often unclear. review it examined how far with different stimulus parameters explained schemes One important conclusion from studies motion vision simple paradigms well complex, behaviorally generated stimuli that improves novel during exposure sustained stimulation. Neuronal might thus facilitate tasks such object detection obstacle avoidance flight.
