Are Myelin Sheaths Magnetic Wormholes ? 

The purpose of this post is to describe how myelin sheaths may act as a neural magnetic hose, and in combination with a neural magnetic cloak may function as a neural magnetic wormhole. This combination could create a “consciousness shielding” or “conscious cloaking” from inspection or interference. 

This post is part three of a three part series describing the possible function of magnetic fields formed by myelin sheaths.  The previous post looked at the magnetic properties of myelin sheaths.

Magnetic Waveguides

This discussion does not include the field “magnonic waveguides”, which is based on high-frequency spin waves running along one-dimensional ferromagnetic material (Lenk 2011). 

A magnetic waveguide is a material structure that acts as a channel for magnetic fields, but it allows magnetic fields to travel outside its boundaries. 

Magnetic Hoses

The functional properties of a magnetic hose are stricter that of a magnetic waveguide because a magnetic waveguide allows the magnetic field to exit outside the bounds of the channel whilst a magnetic hose confines the magnetic field within the channel.  

Navau (2014) created a magnetic hose consisting of alternating concentric cylinders of a high-permeability material (a ferromagnet) and a low-permeability material (a superconductor). The material created a channel that was able to direct magnetic fields over long distances (Anlage 2014). These layers formed a anisotropic meta-material, this mirrors the anisotropic layers in myelin sheaths. It is possible myelin sheaths mirror this functionality

Navau (2014) found a magnetic hose with 6 layers could transfer 80% of the magnetic field. This graph shows a similar number of layers as myelin sheaths.

The inclusion of a soft-and-hard surface lining was found to considerably improve magnetic cloaking and wormholes (Greenleaf 2007a). This mirrors the compaction, lipid and aqueous layers in myelin sheaths. 

Magnetic hoses have been used to create a confined magnetic waveguide where the magnetic flux from multiple static magnets are superimposed in a location away from the static magnets (Sun 2015). This magnetic hose is made of an anisotropic material with very high permeability along its axis with very low permeability perpendicularly.  

Magnetic Wormholes

The idea of an electromagnetic wormhole was first proposed by Greenleaf (2007b). Electromagnetic wormholes “allow the passage of waves between possibly distant regions while most of the region of propagation remains invisible.” … “the wormhole device has the effect of changing the topology of space.” (Greenleaf 2007b).

Prat-Camps (2015) created an electromagnetic wormhole composed of a outer “magnetic cloak” at one end and a magnetic hose that projected from the magnetic cloak. The magnetic wormhole enabled a magnetic field to travel between two places and the field of propagation remained magnetically invisible. The device produced a magnetic monopole at one end of the field. It has been proposed that circular arrays of astrocytes could create a magnetic cloak.

In the design by Prat-Camps (2015) the outer magnetic cloak was a spherical bi-layer in order to shield magnetic fields from all directions. However a cylindrical cloak, instead of a spherical cloak, would still function as a cloak if the fields were from a perpendicular direction. The magnetic hose was composed of a spiral sheet composed of a thin bi-layer of ferromagnetic and superconducting material very much like Navau (2014) above.

Previous posts have described how a magnetic cloak could be formed by a cylindrical array of astrocytes. This post describes how a magnetic hose could be formed by a myelin sheath around an axon. The containment relationship between the cylindrical array of astrocytes and myelin sheath parallels the containment relationship of the magnetic cloak and magnetic hose in the magnetic worm hole design. 

A combination of glia and neurons could create a quasi static  electro or magnetic worm hole that stretches across the neocortex. An additional part of the hypothesis predicts that the field created by Ca+2 would be need to be the main carrier of a quasi static field because it lasts for several seconds underlying spikelets. Further Na+ and K+ would undertake the role of producing short controlling, reset signals between these signs, in the form of action potentials. 


The current hypothesis is that magnetic shielding is created in the brain in the from perpendicular astrocytes and myelin sheaths.  The hypotheses that glial cells shield consciousness from external access or inspection bears out in the lack progress trying to find the neural correlates of consciousness. 

The current hypothesis sketches out a conscious mechanism vaguely along the lines of a “global workspace” (e.g Baars 1997) whereby continuous fields spread across the brain via axons within  myelin sheaths. A magnetic wormhole could produce a distribution mechanism for space-like fields across the neo-cortex, and possibly cerebellum, suggested in previous posts.
