Computational techniques for determining in-vivo threshold currents for magnetophosphenes
Ilkka Laakso, Akimasa Hirata (Nagoya Inst. Techn.)
Abstract (in Japanese) (See Japanese page) 
(in English) Magnetophosphenes are sensations of light that are generated when the human head is exposed to a magnetic field at frequencies around 10 to 50 Hz. Magnetophosphenes are caused by stimulation of the retina by the induced electric current. The human exposure limits in international guidelines are set with the objective of preventing the generation of phosphenes. However, there is still much uncertainty regarding the local threshold currents on the retina. In this study, we use computational methods for analysing the induced current in anatomical human models. The threshold currents are then determined by comparison with previous experimental data.
