Which outcome occurs when a strong magnetic field impedes neuron function?

A)Increased action potential firing rate
B)Inhibition of ion channel gating
C)Enhanced neurotransmitter vesicle release
D)Reduced glial cell metabolic activity

💡 Explanation

Neurons rely on ion channels for signaling, and powerful magnetic fields can disrupt ion trajectories, causing inhibition of ion channel gating because the Lorentz force on ions interferes with normal transport. Therefore, channel gating becomes inhibited rather than augmented, because metabolic activity would be a downstream change.
