NON-IONIZING ELECTROMAGNETIC RADIATION EFFECT ON NERVE FIBER ACTION POTENTIAL OF HUMAN BODY – A REVIEW

The use of electromagnetic radiations (EM) has been increased manifold in recent times mainly due to technological advances. Electromagnetic energy was absorbed by some proportion in the human body which results to an undesirable side-effect. There is a concern on the effect of the electromagnetic radiation on biological systems in general and particularly on human nervous systems. This paper presents a review on non-ionizing electromagnetic radiation effect that has been conducted by various researchers. Through this review, we hope to provide better understanding and awareness on what is essentially happening to action potentials on electrical nerve fiber of human body if there is a presence of interference from non-ionizing electromagnetic radiation

An Empirical Muscle Intracellular Action Potential Model with Multiple Erlang probability Density Functions based on a Modified Newton Method

The convolution of the transmembrane current of an excitable cell and a weighting function generates a single fiber action potential (SFAP) model by using the volume conductor theory. Here, we propose an empirical muscle IAP model with multiple Erlang probability density functions (PDFs) based on a modified Newton method. In addition, we generate SFAPs based on our IAP model and referent sources, and use the peak-to-peak ratios (PPRs) of SFAPs for model verification. Through this verification, we find that the relation between an IAP profile and the PPR of its SFAP is consistent with some previous studies, and our IAP model shows close profiles to the referent sources. Moreover, we simulate and discuss some possible ionic activities by using the Erlang PDFs in our IAP model, which might present the underlying activities of ions or their channels during an IAP.
