    A glial scar formation (gliosis) 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. In the context of neurodegeneration, formation of the ...

[1] The procedure was first performed in 1940 by William P. van Wagenen. [2] In this procedure, the corpus callosum is cut through, in an effort to limit the spread of epileptic activity between the two ...
