概括

人类大脑中成年神经发生 (ANG) 的存在和功能仍在争论中. 这篇论文批判性地检查了当前的研究,敦促人们谨慎对待未经证实的关于大脑再生和神经元替代的说法.

科学领域:

神经科学是一个神经科学.
神经生物学神经生物学神经生物学
大脑的再生大脑的再生

背景情况:

衰老与神经元损失有关,这引发了关于替代机制的问题.
成人神经生成 (ANG) 的概念,即成年大脑中的新神经元的诞生,在人类大脑皮层中尤其具有争议.

研究的目的:

批判性地评估科学证据和关于成人神经生成 (ANG) 的普遍观点.
解决关于老化中的神经元损失,潜在的神经元替代以及成年出生神经元的功能贡献的基本问题.
引导未来的研究方向,并防止无关紧要地接受ANG主张,从而节约资源.

主要方法:

这篇论文是一个反思性的讨论,而不是一个详尽的审查.
它分析了普遍存在的信念,并对ANG研究的当前状况提出了关键的见解.

主要成果:

关于人类ANG的概念和现实,仍然存在严重的混乱和未解决的问题.
对于疾病相关性 (例如,中风后) 的休眠神经前体细胞的重新激活潜力尚未得到确立.

结论:

科学界缺乏关于神经元在衰老过程中丧失的明确解释,以及 ANG 的存在/功能.
需要对ANG的说法进行批判性评估,以避免过分的希望和研究资源的错误分配.
需要进一步进行严格的调查,以澄清 ANG 的状态及其对大脑健康和疾病的影响.

关键词:

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
