Model of Magnetoreception via Lorentz Force on the Transmission of Action Potential along Peripheral Nerves

How animals perceive weak magnetic signals remains a mystery. Here I propose that the sensory inputs can be modulated in their transmission velocity along the peripheral nerves surrounded by Schwann cells which contain huge amounts of superparamagnetic iron nanoparticles stored in ferritins, forming the ordered arrays of hexagonal paracrystalline. Through interparticle interactions within the arrays, the superparamagnetic nanoparticles become subtly magnetized and aligned orderly with the Earths magnetic field. The Lorentz force of the small magnetic field created by the paracrystalline arrays will shift the motion trajectory of cations of action potentials whenever the magnetic line is not parallel to the direction of movement of the ions, from a straight path to a curve track within the myelinated axons. Since bending orientations of the peripheral nerve are always mirror-symmetric, the Lorentz force can delay transmission on one side where the ion trajectory does not fit the axon curve, but has almost no such effect on the other side where the ions can travel along the radian of the axon curve. This mechanism can create a time difference in arrival at the CNS nucleus between the two sides, activating the deviated coincidence detector neurons so that the directions of the external magnetic source are encoded and processed.
