All those years ago I asked a leading neurologist how exactly cerebrospinal fluid circulates and waited for a reply knowing full well that there was no explanation of the driving force. I added that I didn't need to know where it flows from and where it flows to. I just wanted to know what the driving force was? Not a lot to ask is it? Yet neither he nor any other neurologist understands how CSF circulates! Check the physiology books if you don't believe this.
When I asked the question, I knew that my discovery in the circulation in trees and plants applied to the circulation in humans and all animal, even microscopic creatures.
The answer that came back was that it flows from x to x. No description of the driving force was forthcoming. Yet we do understand that posture and respiration is responsible in some way for this circulation that drives and maintains the nervous system.
And then I found this recent paper which identifies gravity as the main driving force for CSF circulation. I have written to the author stating that Brownian Motion is not required to explain a return flow and that the gravity driven down-flow suffices to explain the return flow, sending him my experiment with soft walled tubing, which fits exactly with the image of the CSF flow in the paper! Besides Brownian Motion is multi-directional and therefore cannot focus the flow in any direction.
Background: The authors present the thermodynamic approach to the cerebrospinal fluid circulation.
Methods: On the basis of skin temperature measurements in 16 healthy volunteers a 1.6 ± 0.2 ºC (mean ± SD) difference between the frontal and the lumbar regions has been showed.
Results: Such a temperature difference between both ends of the subarachnoid space in the intracranial and the intracanal compartments can cause natural circulation of cerebrospinal fluid to reach a thermal equilibrium. The cerebrospinal fluid flow is a molecular motion as a consequence of the gravity force and the Brownian movements.
Conclusions: The Brownian motions are the driving forces for the cerebrospinal fluid bulk flow directed upwardly. The gravity force is the driving force for the cerebrospinal fluid bulk flow directed downwardly. The cerebrospinal fluid circulation in the spinal canal is like a corkscrew motion.

This video shows the circulation that led me to Inclined Bed Therapy (IBT)
What does this paper change? It changes the erroneous literature that gravity cannot affect circulation because it acts equally on the descending and ascending limbs of our circulation. This includes blood flow, CSF circulation and Lymph Circulation, along with tissue, bone and muscle circulation. It includes all circulation! No longer can IBT be ignored because it does not fit with published physiology literature.

Gravity and the circulation: "open" vs. "closed" systems.
Hicks JW, Badeer HS.

In contrast, in "closed" systems, like the circulation, gravity does not hinder uphill flow nor does it cause downhill flow, because gravity acts equally on the ascending and descending limbs of the circuit. Furthermore, in closed systems, the liquid cannot "fall" by gravity from higher levels of gravitational potential to lower levels of potential. Flow, up or down, must be induced by some source of energy against the resistance of the circuit. In the case of the circulation, the pumping action of the heart supplies the needed energy gradients. Flow in collapsible tubes, like veins, obeys the same basic laws of liquid dynamics except that transmural pressures near zero or below zero reduce markedly the cross-sectional area of the tube, which increases the viscous resistance to flow."http://www.ncbi.nlm.nih.gov/pubmed/1590467
To say that I am ecstatic about discovering this paper is an understatement.
I look forward to your comments
