髓磷脂通常被比作神经纤维上的电绝缘体。然而,神经冲动并不像电子通过铜线传导那样通过神经元轴突传递,而且髓鞘远不只是绝缘体。髓磷脂从根本上改变了神经冲动(信息)的产生和传递方式,其损伤会导致许多神经系统疾病的功能障碍,包括多发性硬化症、脑瘫、中风、脊髓损伤和认知障碍。因此,对髓磷脂结构的详细了解是必要的,但却是缺乏的。在本期第 319 页,Tomassyet al. 提供了跨越哺乳动物大脑皮层六层的髓磷脂结构的高分辨率全局视图。这些发现可能会引发关于信息如何在大脑中传输和整合的新概念。
Myelin is often compared to electrical insulation on nerve fibers. However, nerve impulses are not transmitted through neuronal axons the way electrons are conducted through a copper wire, and the myelin sheath is far more than an insulator. Myelin fundamentally changes the way neural impulses (information) are generated and transmitted, and its damage causes dysfunction in many nervous system disorders including multiple sclerosis, cerebral palsy, stroke, spinal cord injury, and cognitive impairments. A detailed understanding of myelin structure is therefore imperative, but is lacking. On page 319 of this issue, Tomassyet al.provide a high-resolution global view of myelin structure spanning the six layers of mammalian cerebral cortex. The findings are likely to spark new concepts about how information is transmitted and integrated in the brain.
