Study type: Medical/biological study (experimental study)

A new encephalomagnetic effect in human brain generated by static magnetic fields med./bio.

Published in: Brain Res 1991; 540 (1-2): 295-296

Aim of study (acc. to author)

To test the hypothesis whether a preferred orientation of electric charge movements in the brain of man in static magnetic fields are observable via the magnetic field generated by this charge transport.

Main outcome of study (acc. to author)

Exposure to static magnetic fields as used in NMR-equipment generates a new encephalo-magnetic field in brain of man. The authors found an increased energy when the field after the first exposure was inverted, but only in the frequency band between 6 and 8 Hz. The authors conclude that in the human brain a transfer of electric charges with preferential direction is caused by external magnetic fields.
