Research:  The Fluctuation of the Cerebrospinal Fluid (CSF)

Movement of the Cerebro-Spinal Fluid (CSF) is a well-established phenomenon. CSF flows through the ventricles of the brain and within the spaces around the brain and spinal cord. Sutherland described this motion as fluctuant in nature.

The spinal dural membranes have a notable effect on the flow of CSF.

Summary

Decades of research provide abundant evidence for the fluctuant flow of Cerebro-Spinal Fluid .
