Shared findings of CSF movement in the cranial cavity

In general	Moves, not a circulatory flow.
	Moves, unstable very complex motion.
	Moves, repeats acceleration and deceleration, not only a simple dispersion.
	Related to cardiac gate, respiratory cycle, and daily human activities.
Subarachnoid space	Augmented at ventral surface of the brainstem.
	Strengthened at the center of the cranial cavity, weakened toward the distal part.
	Suppressed in the convexity.
Ventricular system	Augmented in the third and fourth ventricles.
	Suppressed in the trigone.

CSF: cerebrospinal fluid.
