The 150-Year Dogma Broken
UF Health News — 2024 “UF researchers find that cerebrospinal fluid extends beyond the central nervous system” Published in Science Advances. https://ufhealth.org/news/2024/uf-researchers-find-that-cerebrospinal-fluid-extends-beyond-the-central-nervous-system Quote: “This breaks one of the oldest standing dogmas in neuroscience.” CSF flow to peripheral nervous system confirmed in mouse models. Drug delivery implications documented.
The Glymphatic System
Nedergaard et al. — Science (2013) “Sleep Drives Metabolite Clearance from the Adult Brain” Science 342, 373–377 (2013) https://www.science.org/doi/10.1126/science.1241224 Foundational paper. Confirms: 60% increase in interstitial space during sleep. Amyloid-beta clearance rate increase during sleep confirmed. This is the paper that established the glymphatic system.
Iliff and Nedergaard — 2012 Original glymphatic system discovery. University of Rochester. Coined the term “glymphatic.”

Neuronal Waves Drive CSF Clearance
Nature — March 2024 Jiang-Xie LF et al. “Neuronal dynamics direct cerebrospinal fluid perfusion and brain clearance” Nature 627, 157–164 (2024) https://doi.org/10.1038/s41586-024-07108-6 Confirms: synchronised neural action potentials create rhythmic ionic waves that drive CSF perfusion. “Neurons that fire together, shower together.” Blocking neuronal firing prevented waste clearance.
Nature Reviews Neurology — 2024 Kiani, L. “Neuronal activity drives glymphatic waste clearance” https://www.nature.com/articles/s41582-024-00963-x Review of the above study findings.
Sleep and Glymphatic Clearance
Cell — January 2025 Jiang-Xie LF et al. (Nedergaard lab) “Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep” Cell 188 (2025) https://www.cell.com/cell/fulltext/S0092-8674(24)01343-6 Confirms: norepinephrine oscillations at ~0.02 Hz drive vasomotion. Vasomotion acts as pump for CSF. Zolpidem (Ambien) suppresses these oscillations — confirmed. Strongest predictors of glymphatic clearance during NREM sleep confirmed.
PMC — Systematic Review (2021) “Sleep, Cerebrospinal Fluid, and the Glymphatic System: A Systematic Review” PMC: https://pmc.ncbi.nlm.nih.gov/articles/PMC8821419/ 190 articles reviewed, 19,129 participants. Confirms: when sleep is reduced, CSF circulation is reduced. Amyloid-beta and tau elevation with sleep disruption confirmed. Circadian pattern of CSF drainage confirmed.
PMC — Sleep and Glymphatics (2020) “The Sleeping Brain: Harnessing the Power of the Glymphatic System through Lifestyle Choices” https://pmc.ncbi.nlm.nih.gov/articles/PMC7698404/ Confirms: 90% reduction in glymphatic clearance during wakefulness. Twice the protein clearance during sleep. Stage 3 NREM as optimal stage confirmed. CSF oscillations during sleep: 0.05 Hz confirmed. Waking: 0.25 Hz.

Insomnia and reduced waste clearance directly linked.

Alzheimer’s Connection

The Ancient Connection —
Status of Research
No peer reviewed study directly linking ancient “christos oil” traditions to CSF physiology exists.
The connection documented here is structural and observational:
- CSF pulses through the spinal canal rhythmically — documented
- Ancient traditions describe a fluid rising through the spine — documented in religious and esoteric literature
- The connection between them is a theoretical parallel — not a confirmed research finding
Tag remains: theory Do not cite as verified. Hold as open question for future investigation.
Still To Source
- Respiratory contribution to CSF flow — specific studies on breathing practices and CSF dynamics investigate
- Physical movement and CSF — yoga and spinal movement studies on glymphatic function investigate
- Ancient texts specifically describing spinal fluid — primary source citations in Gnostic, Kabbalistic, or early Christian literature investigate
- EMF effects on glymphatic function — does synthetic electromagnetic exposure disrupt sleep architecture specifically at the level of norepinephrine oscillations? Not yet studied directly. #investigate
- Fluoride and choroid plexus — does fluoride accumulation in the choroid plexus affect CSF production or quality? #investigate — connects to Fluoride note
