In the case of brain death, it liquefies.
In the case of lesser degrees of damage, such as persistent vegetative states, the brain generally atrophies and functional cortex is replaced by the brain's version of scar tissue.
Scar tissue in the brain is not dense like a keloid in the skin. It's just atrophy and replacement of functional neuronal tissue by non-conducting cells that can have no CNS functional activity.
And the non-conducting cells wouldn't last forever without any cerebral perfusion either.
