Brains React To Earth’s Magnetism

Some researchers have found evidence that certain humans can perceive magnetic fields in a subtle way, even when they do not consciously notice anything. In laboratory tests, participants sat quietly while scientists changed magnetic field conditions to mimic shifts in Earth’s geomagnetic field. The researchers measured brain activity and saw reactions that tracked those geomagnetic changes. The results suggested the brain can register magnetic-field information without the person feeling an obvious sensation.
