AI Thread Summary
Nerve fibers in the brain are indeed covered by myelin, although this myelination process occurs later in human development. Unlike the peripheral nervous system, where nerve fibers are surrounded by perineurium, the brain's nerve fibers are supported by a complex environment that includes not only myelin but also various types of connective tissue, support cells, immune cells, vascular cells, and an extracellular matrix. This intricate network plays a crucial role in maintaining the structure and function of the brain's nerve fibers.

Hello everyone,

I know nerve fibres inside brain are not covered by perineurium etc like Peripheral nervous system. Are they still covered with connective tissue, support cells, myelin etc. I mean inside the brain , a collection of nerve fibres, how are they held together with no connective tissue. I don't have much knowledge about brain. Thanks :smile:

Not for all fibers. For most, though.
 
There is a lot more in the brain than just nerve cells, if that's what you're getting at. Immune cells, vascular cells, extracellular matrix, ...
 
I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
