Many workers have suggested that the crayfish giant fibers trigger swimming movements or tail flips during escape responses. Recordings from intact animals show that this is often not the case; both swimming and single tail flips can occur in the absence of giant fiber activity. Swimming movements and tail flips are coordinated by neural mechanisms not involving the giant fibers. When giant fibers are active, they may trigger the first flexion in a swimming sequence, initiate a single tail flip, or synchronize the muscular activity in the several segments of the abdomen, but they are not a necessary part of the neural oscillator which drives swimming.
许多研究人员认为，小龙虾的巨纤维在逃避反应中触发游泳动作或尾部翻转。对完整动物的记录表明，情况往往并非如此；在没有巨纤维活动的情况下，游泳和单次尾部翻转都可能发生。游泳动作和尾部翻转是由不涉及巨纤维的神经机制协调的。当巨纤维活跃时，它们可能会触发游泳序列中的第一次弯曲，引发单次尾部翻转，或使腹部几个节段的肌肉活动同步，但它们并不是驱动游泳的神经振荡器的必要组成部分。
