Abstract
The effects of electromagnetic field (EMF) exposure on biological
systems have been studied for many years, both as a source of medical
therapy and also for potential health risks. In particular, the
mechanisms of EMF absorption in the human or animal body is of
medical/engineering interest, and modern modelling techniques, such as
the Finite Difference Time Domain (FDTD), can be utilized to simulate
the voltages and currents induced in different parts of the body. The
simulation of one particular component, the spinal cord, is the focus of
this article, and this study is motivated by the fact that the spinal
cord can be modelled as a linear conducting structure, capable of
generating a significant amount of voltage from incident EMF. In this
article, we show, through a FDTD simulation analysis of an incoming
electromagnetic field (EMF), that the spinal cord acts as a natural
antenna, with frequency dependent induced electric voltage and current
distribution. The multi-frequency (100-2400 MHz) simulation results show
that peak voltage and current response is observed in the FM radio range
around 100 MHz, with significant strength to potentially cause changes
in the CNS. This work can contribute to the understanding of the
mechanism behind EMF energy leakage into the CNS, and the possible
contribution of the latter energy leakage towards the weakening of the
blood brain barrier (BBB), whose degradation is associated with the
progress of many diseases, including Acquired Immuno-Deficiency Syndrome
(AIDS).
