Abstract
  1. Neurochemical events associated with the retention of learning through metamorphosis in the tenebrionid beetle, Tenebrio obscurus, were investigated. 2. Retention of learning of a complex maze task was demonstrated for this species. 3. Learning was accompanied by a significant increase in RNA synthesis within the corpora pedunculata of both larval and adult stages of this holometabolous insect. 4. The implications of these results to the development of the insect CNS during various life cycle stages and the conservation of neural organization within those brain regions associated with the consolidation and storage of experiential information are discussed.
摘要
  1. 对黄粉虫(Tenebrio obscurus)变态过程中与学习记忆相关的神经化学事件进行了研究。2. 已证明该物种能够保留复杂迷宫任务的学习记忆。3. 在这种全变态昆虫的幼虫和成虫阶段,学习过程伴随着蕈形体中RNA合成的显著增加。4. 讨论了这些结果对于昆虫中枢神经系统在不同生命周期阶段发育的意义,以及与经验信息巩固和存储相关的脑区中神经组织的保守性。
