Abstract: The global compliance of a fixed-volume, incompressible compartment may play a significant role
in determining the inherent vascular compliance. For the intracranial compartment, we propose that the free-
displacement of the cerebral spinal fluid (CSF) directly relates to cerebral vascular compliance. To test this
hypothesis, an in vivo surrogate intracranial compartment was made by enclosing a rabbit's kidney within a
rigid, fluid-filled container. Opening/closing a port atop the box modulated the free flow of box fluid (open-box
state). We observed that the pulsatility of the renal venous outflow increased in response to hampering the
