The emergence of the adult cecropia silk moth from the pupal skin involves a stereotyped series of abdominal movements-the pre-eclosion behavior. This behavior, triggered by a neurosecretory hormone, consists of three phases that are characterized by the relative frequency and pattern of movements. Electrical recordings from a nerve cord with severed peripheral nerves demonstrate that the pre-eclosion behavior is prepatterned in the abdominal ganglia. In response to the hormone, the entire 1.25-hour behavioral program can be activated and "read off" in the absence of sensory feedback.
成年天蚕蛾从蛹皮中羽化出来时，会进行一系列固定模式的腹部运动——羽化前行为。这种行为由一种神经分泌激素触发，包括三个阶段，其特点是运动的相对频率和模式。对切断外周神经的神经索进行电记录表明，羽化前行为在腹神经节中预先设定好了模式。在激素的作用下，整个1.25小时的行为程序可以在没有感觉反馈的情况下被激活并“读出”。
