The third pair of legs of the primitive New Zealand orthopteran insect, the " weta ", has and innervation and muscle cell distribution exactly similar to that of locusts, but wetas do not jump. Neuromuscular transmission to the slow excitatory axon ( SETi ) is potentiated more than 10-fold by the natural modulator octopamine (OCT). A brief burst of SETi impulses following infusion of as little as 10(-8) M OCT is followed by a very long-lasting plateau of catch-like tension (CT). The plateau is abruptly relaxed by a single inhibitory impulse, or even by a single SETi impulse if this arrives no sooner than about 30 sec following excitation. CT is used by wetas in a defense posture. Locusts and grasshoppers have a different type of modulation by OCT.
新西兰原始直翅目昆虫“沙螽”的第三对腿具有与蝗虫完全相似的神经支配和肌肉细胞分布，但沙螽不会跳跃。天然调节剂章鱼胺（OCT）可使向慢兴奋性轴突（SETi）的神经肌肉传递增强10倍以上。注入低至10^(-8) M的OCT后，SETi冲动的短暂爆发会引发持续时间很长的类似捕捉的张力（CT）平台期。单个抑制性冲动，或者如果在兴奋后不早于约30秒到达的单个SETi冲动，都能使该平台期突然松弛。沙螽在防御姿势中会利用CT。蝗虫和蚱蜢对OCT有不同类型的调节作用。
