We are continuously exposed to electromagnetic (EM) fields generated by electronic devices such as cell phones. The effects on human bodies by EM waves, especially ones with the frequency range between 3 kHz and 300 GHz, called radiofrequency (RF), are of great interest. Reported effects of RF fields on living systems are widely variable; harmful, negligible, or nil. Although no definitive evidence has been found, it is generally considered that exposure to low energy RF waves could be a risk to human health. However, some beneficial effects were also reported. The project I joined is to elucidate the underlying mechanism of the effects of the EM fields to the neurons. I originally attempted to work on a part of the top-down approach; how the generated EM waves near the head penetrate the skull, how the network of the neurons are stimulated (extracellular stimulus), and then if the action potentials occur in each of the neurons. This approach was, however, very difficult, so I worked on a part of the bottom-up approach instead; I explored by simulation what kind of intracellular stimulus would be the most efficient to generate action potentials on a single neuron
