在静止飞行中，果蝇对视觉运动刺激产生偏航力矩。突变optomotor-blindH 31（omb），它缺乏水平（HS）和垂直（VS）的巨大纤维在小叶板的剩余optomotor偏航力矩响应，不同于野生型在几个方面：它是限制在正面的视野，它只引起由前到后的运动，似乎是介导的一组不同的基本运动检测器（EMD）。使用一个单一的黑色条纹作为运动刺激的扭矩响应，即使在野生型苍蝇，占主导地位的正面视野和由前到后的运动。因此，我们建议果蝇的视觉运动偏航控制组织为两个部分平行的亚基。仍由omb显示的成分被称为“对象响应”;突变体中缺失的成分（推测是由野生型中的巨大HS细胞介导的）被称为“大视野响应”。描述了对象响应的几个属性。
In stationary flight Drosophila melanogaster produces yaw torque in response to visual movement stimuli. The residual optomotor yaw torque response of the mutant optomotor-blindH31 (omb), which lacks the horizontal (HS) and vertical (VS) giant fibers in the lobula plate, differs from that of wild-type in several aspects: it is restricted to the frontal visual field, it is only elicited by front-to-back motion and appears to be mediated by a different set of elementary movement detectors (EMDs). Using a single black stripe as motion stimulus the torque response is, even in wild-type flies, dominated by the frontal visual field and by front-to-back motion. We thus propose that Drosophila''s optomotor yaw control is organized as two partially parallel subunits. The component still displayed by omb is called "object response"; the component missing in the mutant (which is presumably mediated by the giant HS-cells in the wild-type) is called "large field response". Several properties of the object response are described.
