A probably related observation found on the wikipedia page about sonoluminescene that oscillations driven by an external periodic force often have a more stable period than the external force. In this case a neuron is a driving force and the magnetic field is the oscillating "water" that has a period more stable, and thus preserves information better than the neuron itself.
