A member asked:

How much space/cushioning is in between the brain and skull (in units)? how does the cushioning protect the brain from everyday head movements?

Dr. Charles Gordon answered

Specializes in Adolescent Medicine

0.5-1 cm: The brain is surrounded by cerebrospinal fluid. It does not touch the inside of the skull. So when the head is "jerked" the brain floats in the CSF and the blow is cushioned. It goes back to the physics. A fluid cannot sustain a pressure gradient.

Dr Altman and another doctor agreed
