Global InformationMagnetophosphene information
Magnetophosphenes are flashes of light (phosphenes) that are seen when one is subjected to a changing magnetic field such as when in an MRI. This changing field causes current within the retina or visual cortex resulting in the illusion of light.[1] In one series, 8 out of 1023 people having an MRI experienced flashing lights.[2]
Magnetophosphenes have been proposed as an explanation for ball lightning.[3]
