Earthworms are segmented invertebrates that belong to the phylum Annelida. The segments can be divided into the anterior, clitellar and posterior parts. If the anterior part of the earthworm, which includes the brain, is amputated, the worm would essentially survive even in the absence of the brain. In these brain amputee-derived worms, the nerve cord serves as the primary control center for neurological function. In this current work, we studied changes in the expression levels of anti-acetylated tubulin and serotonin as the indicators of neuro-regenerative processes. The data reveal that the blastemal tissues express the acetylated tubulin and serotonin from day four and that the worm amputated at the 7th segment takes 30 days to complete the regeneration of brain. The ability of self-assemblage is one of the specific functions of the earthworm’s brain. The brain amputee restored the ability of self-assemblage on the eighth day.

Eu Eudrilus eugeniae的中枢神经系统再生和社会能力研究。

are是属于无核纲门的无节段的无脊椎动物。这些部分可分为前部，cli骨部和后部。如果将包括大脑在内的worm的前肢切除，即使没有大脑，该essentially也将基本存活。在这些脑部截肢者蠕虫中，神经线是神经功能的主要控制中心。在当前的工作中，我们研究了抗乙酰化微管蛋白和5-羟色胺的表达水平的变化，这些变化是神经再生过程的指标。数据显示，胚盘组织从第四天开始表达乙酰化的微管蛋白和5-羟色胺，在第7段截肢的蠕虫需要30天才能完成大脑的再生。自组装能力是worm大脑的特定功能之一。大脑截肢者在第八天恢复了自我组装的能力。
