The middle layer of the brain with cottony fibers is likely referring to the arachnoid mater, one of the meninges that surround the brain. It is a delicate, web-like membrane filled with thin, fibrous strands that provide cushioning and support for the brain.
The arachnoid mater forms the middle layer of the meninges. It consists of delicate, web-like fibers that lie between the dura mater and the pia mater.
subarachnoid space
middle layer of meninges is called arachnoid
The arachnoid mater is the middle layer of the meninges that forms a loose covering over the brain. It is located between the dura mater (outer layer) and the pia mater (inner layer) of the meninges.
The middle element of the meninges is the arachnoid membrane
Collagenous fibers are the tough fibers of connective tissue.

the three layers of meninges are as follows: Outer layer(layer closet to the skull): known as the Dura Mater. Middle layer: known as the Arachnoid Inner layer(layer closest to the cerebral cortex): known as the Pia Mater ***The meninges contain cerebral spinal fluid (which is produced in the brain stem) which as a shock absorber. The meninges also provide extra support and protection for the brain.controls involuntary muscle
The subdural space contains a thin layer of fluid known as the subdural fluid, which helps cushion and protect the brain from sudden movements or impacts. This space is located between the dura mater (outermost layer of the meninges) and the arachnoid mater (middle layer of the meninges) surrounding the brain.
The outermost layer of meninges is called as Dura matter. It has got outer and inner layers in Dura matter. Together they form various venous sinuses in the meninges.
