Low-frequency pulsed electromagnetic field exposure can alter neuroprocessing in humans
Authors not listed · 2009
An fMRI study found that low-intensity low-frequency magnetic fields alter brain activation in the right insula, anterior cingulate, and bilateral hippocampus/caudate during thermal pain processing in humans.
Plain English Summary
Extremely low-frequency magnetic fields from DC to 300 Hz have been shown to affect pain sensitivity in snails, rodents, and humans. In this fMRI study, researchers exposed normal volunteers to extremely low-frequency magnetic fields and measured brain activation during acute thermal pain. Significant interactions between pre- and post-exposure activation were found between sham and exposed groups in the ipsilateral right insula, anterior cingulate, and bilateral hippocampus/caudate areas.
Why This Matters
The results show for the first time that neuromodulation from low-intensity low-frequency magnetic fields can be observed in humans using functional brain imaging, and the detection mechanism may differ from that used by animals for orientation and navigation. The study notes that magnetoreception may be more common than presently thought.
