我们提供的证据轴突再生的中枢神经系统（CNS）的蝗虫（蝗虫migratoria）。我们遵循的形态学的一小组proctolin免疫反应神经元在腹神经索之前和之后，粉碎一个在第三龄的宫颈结缔组织。近端段开始发芽后3天内病变，并在9天内生长到食管下神经节，覆盖约2毫米的距离。在食管下神经节内，再生的神经突形成树枝状在适当的区域，非常类似于原来的形状。这些发现将使我们能够将再生与这种动物中轴突连接的良好描述的胚胎发育进行比较。(C)2004 Elsevier B.V.保留所有权利。
We provide evidence for axonal regeneration in the central nervous system (CNS) of the locust (Locusta migratoria). We followed the morphology of a small set of proctolin-immunoreactive neurons in the ventral nerve cord before and after crushing one cervical connective in the third instar. The proximal segments started sprouting within 3 days post lesion and grew into the suboesophageal ganglion within 9 days, covering a distance of approximately 2 mm. Within the suboesophageal ganglion, the regenerated neurites formed arborisations in the appropriate region which closely resemble the original shape. These findings will allow us to compare regeneration to the well-described embryonic development of axonal connectivity in this animal. (C) 2004 Elsevier B.V. All rights reserved.
