The ventral nerve cord of holometabolous insects is reorganized during metamorphosis. Certain elements, however, persist from the larval to the adult stage. A group of dorsal unpaired median neurons and a set of thoracic serotonin-immunoreactive interneurons are shown to be persistent elements in the ventral nerve cord of Tenebrio molitor. These persistent neurons retain their "bauplan" even after deprivation of the sensory neurons projecting onto them. These persistent neurons might provide a network into which newly developing sensory neurons fit during reorganization of the nervous tissue.
全变态昆虫的腹神经索在变态过程中会发生重组。然而，某些元件会从幼虫阶段持续到成虫阶段。在黄粉虫的腹神经索中，一组背侧不成对的中间神经元和一组胸部5-羟色胺免疫反应性中间神经元被证明是持续存在的元件。即使投射到这些持续存在的神经元上的感觉神经元被剥夺，它们仍保留其“基本结构”。这些持续存在的神经元可能提供一个网络，在神经组织重组过程中，新发育的感觉神经元可以融入其中。
