家蝇的“时钟尖峰”是由位于筋膜下神经节的运动神经元产生的。它支配一个小肌肉，附着在视网膜的内额缘。在额眼区域，肌肉活动导致远端横纹肌尖端垂直于小眼轴移动。由此导致小网膜细胞的光轴的缓慢角运动。各种肉眼视觉刺激可以轻微改变尖峰频率。足够的视觉刺激以及眼肌系统的功能意义，相对于不受限制的昆虫的行为仍然是未知的。
“Clock-spikes” in Musca are produced by a motoneurone which lies in the subesopha-geal ganglion. It innervates a small muscle, attached to the inner frontal margin of the retina. In the frontal eye region, muscular activity causes the distal rhabdomere tips to move perpendicular to the ommatidial axes. Slow angular movements of the optical axes of the retinula cells result herefrom. The spike rate can be slightly changed by a variety of gross visual stimuli. The adequate visual stimulus as well as the functional significance of the eye muscle system with respect to the behaviour of the unrestrained insects are still unknown.
