Brain injury will commonly be accompanied by acute swelling, which impairs function in brain tissue that remains alive. Resolution of swelling is an important factor for the individual's function to improve. The greatest factor in functional recovery after brain injury comes from the brain's ability to learn, called neuroplasticity. After ...
A glial scar formation is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system.As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the healing process in the nervous system.
Further breakdown of the blood–brain barrier, in turn cause a number of other damaging effects such as swelling, activation of macrophages, and more activation of cytokines and other destructive proteins. Astrocytes can heal partially the lesion leaving a scar. These scars (sclerae) are the known plaques or lesions usually reported in MS.
This process leaves cells destroyed or collapsed, and a distinctive silvery or bronze scarring on the surfaces of the stems or leaves where the thrips have fed. [16] The mouthparts of thrips have been described as “rasping-sucking”, [ 17 ] “punching and sucking”, [ 11 ] or, simply just a specific type of “piercing-sucking” mouthparts.
Take care not to use too much fertilizer, though, as overfertilizing can cause plants to produce new, tender growth, which attracts thrips. Related: The 10 Best Fertilizers for Indoor Plants of ...
Micrograph showing gliosis in the cerebellum. Reactive astrocytes on the left display severe proliferation and domain overlap. Reactive astrogliosis is the most common form of gliosis and involves the proliferation of astrocytes, a type of glial cell responsible for maintaining extracellular ion and neurotransmitter concentrations, modulating synapse function, and forming the blood–brain ...
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area.It is common for both focal and diffuse damage to occur as a result of the same event; many traumatic brain injuries have aspects of both focal and diffuse injury.
