成年鸣禽前脑内的神经元再生

Neurogenesis in the Telencephalon of Adult Songbirds

成年鸣禽前脑的某些区域具有神经元的再生现象 .神经元的再生由室层区的细胞经迁徙、分化形成 .新生神经元可作为一种功能成分参与鸣啭控制通路的组成 ,成年再生的神经元是鸟类鸣啭可塑性的结构基础之一 .成鸟脑内的神经元再生现象打破了传统的神经元数目只能减少 ,不能增加的观念 .

Neurogenesis occurs in some areas of the telencephalon of adult songbirds. The new neurons born in the walls of the lateral ventricle migrate and differentiate throughout the tolecephalon, and may make up to the song control system. The new neurons are one of the basic structures that form the plasticity of bird song. The neurogenesis in adult birds breaks the traditional ideas that the number of neurons may decrease but can not reduce.
