On the fine structure of yaw torque in visual flight orientation ofDrosophila melanogaster (original) (raw)
Summary
Facing two or more moving objects in stationary flight_Drosophila_ can restrict its torque response to one of them. Under such conditions it evaluates stimuli only in certain parts of the visual field. For the sake of brevity we call this ‘visual attention’. The fly is able to focus its ‘attention’ to any angular position (in the horizontal). In this process it follows the stimuli presented.
In contrast, the optomotor control system, which adjusts the optomotor balance of the fly is mostly, if not always, sensitive at the same time to the movements of several objects in different parts of the visual field.
