What fundamental process might fluctuating magnetic fields influence according to biological hypotheses regarding nerve transmission?

Answer

Ion transport across cell membranes.

Research suggests that when the Earth's magnetic field is disturbed, the resulting low-frequency magnetic fields might interact with biology by influencing ion transport across cell membranes, a fundamental process in nerve signal transmission.
