The effect of exogenously induced magnetic fields on neurotransmitter dynamics

Abstract

Over the past decades, there has been significant controversy regarding the role of exogenous electromagnetic (EM) fields on the dynamics of molecules in living cells. Here we present a model of electromagnetic forces in the synaptic cleft using the bidomain theory as a framework and the averaged field theory as the theoretical basis, suggesting that the exogenously induced magnetic field may modify the neurotransmitter dynamics. Our model is based on a voltage cell membrane amplification due to the Hall effect principle and the hypothesis that synaptic cleft electric conductivity is represented by tensors with non-zero off-diagonal terms. The physical interpretation of the off-diagonal components is explained, and analytical expressions for the induced magnetic field and conductivity tensor are derived.
