Injection of S-antigen (arrestin) antibody into the brain of the blow fly, Calliphora vicina, appeared to reduce sensitivity to the photic effects of a light:dark cycle (LD; entrainment) or continuous "bright" light (LL; arrhythmicity). In LD, a proportion of the injected flies evaded entrainment or showed delayed entrainment. In bright LL, flies continued with a free-running rhythm, which remained unchanged (as in continuous darkness) or lengthened (as in "dim" LL). These results focus attention on four groups of arrestin-positive neurons in the fly's brain as potential components of the photoreceptive system.
将S抗原（抑制蛋白）抗体注射到红头丽蝇（Calliphora vicina）的大脑中，似乎会降低其对明暗周期（LD；同步化）或持续“明亮”光（LL；无节律性）的光效应的敏感性。在LD条件下，一定比例的注射苍蝇逃避同步化或表现出延迟同步化。在明亮的LL条件下，苍蝇继续保持自由运行节律，该节律保持不变（如同在持续黑暗中）或延长（如同在“昏暗”的LL条件下）。这些结果将注意力集中在苍蝇大脑中四组抑制蛋白阳性神经元上，认为它们是光感受系统的潜在组成部分。
