<p>Would like to disagree with <a href="https://psychology.stackexchange.com/a/6553/21">anongoodnurse's answer</a> when it states that <em>"there are no indications of a CSF fluid pump"</em>.</p>

<p>CSF fluid is affected by cardiovascular pulse wave in the rhythmic brain motion during the systolic expansion.

Hi Pascal. This doesn't disagree with my answer at all, in which I quote a source, "By employing this respiration-induced spin labeling bSSFP cine method, we were able to visualize CSF movement induced by respiratory excursions. CSF moved cephalad (16.4 ± 7.7 mm) during deep inhalation and caudad (11.6 ± 3.0 mm) during deep exhalation in the prepontine cisternal area. Small but rapid cephalad (3.0 ± 0.4 mm) and caudad (3.0 ± 0.5 mm) movement was observed in the same region during breath holding and is thought to reflect cardiac pulsations."

Also, you cited the same paper I used in my answer. "It is something of a misnomer to speak of CSF “circulation”, particularly in the spinal canal, as there is no continuous loop circulation of CSF as in the cardiovascular system. The spinal CSF fluctuates in biphasic tides of cephalic ebb and caudal flow."

@StevenJeuris - There are diseases affecting cerebrospinal fluid 'circulation' (using the word correctly in context), but the paper, while identifying correctly (to allopathic understanding) CSF formation, distribution, etc, it deviates in treatment of CSF problems. Note that one author is "the founder of Cerebrospinal Fluid Technique Seminars" - likely a for profit enterprise, making this paper content subject to conflict of interest.

[The Wikipedia article you link to](https://en.wikipedia.org/wiki/Cerebrospinal_fluid) states that _"[f]luid movement is pulsatile, matching the pressure waves generated in blood vessels by the beating of the heart. Some authors dispute this, posing that there is no unidirectional CSF circulation, but cardiac cycle-dependent bi-directional systolic-diastolic to-and-fro cranio-spinal CSF movements."_ (at least when I wrote this comment, might not have been there several years ago ;p)

The "circulation" of the CSF, as already mentioned, is something of a misnomer. CSF is not known to "circulate" in the manner of blood. It does get *agitated* by pressure differentials, and it is 'circulated' in terms of being reabsorbed and replaced every 6-7 hours. Other than that, no circulation occurs.

*Blood* circulation is not generated only by the heart. Pressure differentials throughout the body affect the circulation of blood as well. One that is easily demonstrated (first documented in 1733) is the effect of intrathoracic (chest) pressure on circulation. The blood pressure of healthy people falls during spontaneous inspiration. When someone takes a deep breath, the blood return to the heart via the vena cava decreases, and pressure is exerted on the right atrium. Both cause decreased filling, which will drop blood pressure. Although this is best demonstrated with a blood pressure cuff, it can be demonstrated without. An unrecommended method is exemplified in a childhood game of *passing out*. A Valsalva maneuver (deep breath and glottal closure) decreases blood flow to the heart. Squeezing the chest further decreases return, resulting in fainting.

The same pressure differentials agitate the CSF. Additionally, smaller movements were seen with pressure differentials caused by the beating of the heart.
