Revealing the Imperceptible Network: Numerical Studies on the Impact of Electromagnetism on the Human Brain

Recent advancements in radiofrequency electromagnetic field communication have raised questions about their potential impact on biological tissues, particularly the human brain. Our study aims to numerically examine the influence of these electromagnetic fields on the human brain. For this purpose, we used a numerical modeling approach that integrates the human brain as the internal medium and a cell phone as the external source of radiofrequency. The methodology is based on Maxwell’s equations and the finite element method to discretize our model, complemented by boundary integral techniques. Our results show the behavior and intensity of the electric and magnetic fields inside the brain as a function of distance. Furthermore, we aim to understand their influence on the action potential, which is in the millivolt range, with frequencies between 0.1 and 100 Hz.
