All of our brains are bathed in cerebral spinal fluid--yours, mine, and Mrs. Schiavo's. In effect, all of our brains are sloshing around in a liquid inside our skulls.
Mrs. Schiavo has significant reduction in brain tissue mass (atrophy). Thus she has more CSF:brain matter ratio than you or me.
I see. I guess I mis-spoke. I understand the whole cerebral fluid in the skull etc.
It's just the impression I get when I hear some MSM talking head say her brain is "liquified" that her brain...gray matter/brain tissue and all is just sloshing around in her head like a milkshake.
