摘要：

When the gaze is moved quickly, vision becomes blurred and the way in which three-dimensional structures are seen can be affected1. How can these effects be minimized? During flight, blowflies (Calliphora vicina) turn both the head and the thorax very quickly, producing gaze shifts which affect vision. Here we show that blowflies reduce the effects of thorax movements on vision by moving the head later, and more quickly, than the thorax. This reduces the time in which gaze is shifting relative to the surroundings, and maximizes the time available for analysing the surroundings.
