View Original AbstractStrong pulsed magnetic fields from MRI-level equipment showed no immediate effects on brain visual processing in this controlled study.
Plain English Summary
Researchers exposed seven people to strong pulsed magnetic fields (similar to those in MRI machines) while measuring their brain's visual processing responses. They found no significant changes in how the brain processed visual information during or after the 10-minute exposure. This contradicts some earlier studies that found effects from different types of magnetic field exposure.
Study Details
To study the effect of switched magnetic fields used in MR scanners on the visual evoked potential (VEP) in human subjects.
We have used an MRI gradient coil, remote from an MRI magnet to produce a time‐varying magnetic fiel...
In contradiction to studies previously reported in the literature for fields of 50 Hz and 60 mT, no ...
Switched magnetic fields of a level and frequency comparable to those used in MRI do not have a significant effect on primary retinal or visual processing
