研究了在踏轮上行走的个体竹节虫。当一条腿抓住轮子旁边的一个小的固定杆时，它：（a）施加一个有节奏地调制的向后指向的力（调制频率与其他腿的步进频率相同）;或（B）在最小力阶段定期抬起棍子，然后返回棍子;或（c）踩在轮子上。如果车轮停止，则施加的力增加。据推断，这种行为是由未知来源的中央节律性。这种行为的所有已知感觉输入都叠加在这个中枢振荡上。一个假设进行了讨论，定性地适合所有的实验结果上的效果，这些感官的影响，对一个人的腿的动作在坚持昆虫的时间。
Individual stick insects were studied walking on a tread‐wheel. When a leg caught hold of a small fixed rod beside the wheel it: (a) applied a rhythmically modulated backward directed force (with the modulation frequency identical to the stepping frequency of the other legs); or (b) regularly lifted off the stick during the phase of minimum force, and then returned to the stick; or (c) it stepped onto the wheel. If the wheel was stopped, the applied force increased. It is deduced that this behaviour is driven by central rhythmicity of unknown origin. All the known sensory inputs to this behaviour are superimposed on this central oscillation. A hypothesis is discussed which qualitatively fits all the experimental results on the effect of these sensory influences on the timing of an individual leg's movements in stick insects.
