Plasticity of Visuo-Motor Coordinationustment of the closed loop gain for the guidance of eye movements. Even most severe distortions of visuo-motor coordination such as are imposed by goggles which invert the whole visual scene upside down or left to right can be compensated by experience (Stratton, 1897; Kohler, 1956).

Synopsis moving flies are intimately interwoven. At the first level the fly stabilizes its orientation against internal and external perturbations, at the second level it chooses a certain orientation with respect to landmarks and thirdly, it adapts its orientation to the pursuit of an objective.

Flying StraightThe simplest answer to this question would be that the mechanisms work permanently as long as the fly is confronted with visual motion (cf. Chap. 3; Optomotor Equilibrium). We will see in the second part of this book, however, that course control is more sophisticated. Even the basic function is modified according to more general requirements.

Foreground—Background Experiments stationary object, or from movement of the object itself. The fly cannot distinguish between these possibilities. It has to take its chances. We now turn to more complex visual stimuli which lessen the ambiguity for the fly.

要塞

Introductionmparative studies of small animals, stimulus—response chains are considered the hard core of visual behavior. Our experience as humans with vision as a continuous series of verifications or rejections of guesses is taken as a specialty of higher vertebrates.
