These cells are essential for neurons to communicate with one another because they insulate the long axons between neurons , preventing the electrical signal carried by the axons from dissipating 这些细胞会包围在神经细胞的长轴突外，使它们彼此绝缘，如此可防止轴突所携带的电讯号消散开来，因此寡突细胞是神经细胞互相沟通所不可或缺的。
This fact led me to speculate that an axon could find its retinal cell neighbors in the tectum by homing in on chemical scents released by active tectal neurons , because its neighbors were most likely at the source of this trail 这让我怀疑，轴突是否可以藉著活跃的顶盖神经元释出的化学物质，找到顶盖里的视网膜细胞邻居，因为它的邻居最有可能就在这条路的起点。
Kenyon cells are not labeled . in the back of the protocerebrum , there are two groups ( about 20 ) of large positive neurons whose axons often run in bundles , some thin branches of which invade a large area of the protocerebrum 在前脑后侧，靠近蕈形体冠的下方，有对称分布的两组大的抗原细胞，在食道孔上方形成许多纤维束并且分枝向侧前脑，前脑下方扩展，形成大量的阳性纤维。
Topics include : neural induction and pattern formation , cell lineage and fate determination , neuronal migration , axon guidance , synapse formation and stabilization , activity - dependent development and critical periods , development of behavior 主题包括：神经诱导和模式形成，细胞谱系和细胞命运确定，神经元迁移，轴突引导，突触的形成和稳定性，依赖性活动的发育和危险期，行为的发育。
