In Calliphora erythrocephala the visual fixation behaviour in one-eyed flies and partial blinded flies has been investigated. One-eyed flies show approximately the same stripe and edge fixation response as intact flies. Elimination of the frontal eye parts including the binocular field of vision does not effect the visual stripe fixation. On the other hand, if only the frontal areas of both eyes including the binocular field of vision are left open, no preferential direction can be observed (Fig. 1--3). The results imply the existence of a fixation-sensitive area of the eye located outside the binocular field of vision.
在红头丽蝇中，对独眼蝇和部分失明蝇的视觉固定行为进行了研究。独眼蝇表现出与完整苍蝇大致相同的条纹和边缘固定反应。去除包括双眼视野在内的额眼部分不会影响视觉条纹固定。另一方面，如果仅保留包括双眼视野在内的双眼额叶区域，则观察不到优先方向（图1 - 3）。结果表明，在双眼视野之外存在一个眼睛的固定敏感区域。
