| summary | Magnetophosphenes are a visual perception, described to be colourless flickering lights occurring upon exposure to an alternating magnetic field, oscillating between 10 and 100 Hz. Magnetophosphenes are caused by the induction of electric fields and currents in the retina, but the characteristics of the frequency dependence of this perception is still not well established nor understood. This work is testing magnetic fields ranging from 20-300 Hz, with stimuli intensities up to 80 mT. Phosphene perception thresholds and electroencephalography (EEG) are recorded and analysed. Knowing and understanding the cascade of events leading to this perception have a direct impact on international safety and exposure guidelines protecting the workers and general public health, and open the way to translational diagnosis or neuromodulation applications. |
