Scientific experiment found human “sixth sense”

  Birds, insects and some mammals have been shown to have the ability to sense the earth’s magnetic field, which they use to locate and migrate.
  There have always been two main views on how animals perceive the earth’s magnetic field:
  One view is that the earth’s magnetic field can trigger a quantum reaction in a protein called “cryptochrome”. These proteins have been found in the retinas of birds, dogs, and even humans, but it is unclear how they feed magnetic information back to the brain.
  Another view is that there are actually receptor cells in the human body, which contain very thin “compass needles”. These compass needles are made of magnetic iron minerals called magnetite. They move according to the direction of the earth’s magnetic field. Directional. Scientists have found magnetite in cells in bird beaks and trout noses, but again, this ability cannot be fully explained.
  For a long time, some scientists believe that the human brain also has the ability to sense the earth’s magnetic field-this is called the “sixth sense”, but there is no experimental support. Recently, Kilshwink, a geophysicist at the California Institute of Technology in the United States, confirmed that the human brain does have a certain degree of “sixth sense”-the ability to perceive the earth’s magnetic field in a certain subconscious way.
  Before him, some researchers have done experiments on human “magnetic sensation”, but these experiments have not been effectively replicated (under the same experimental conditions, the results of each experiment are different). The researchers attributed it to electromagnetic interference, which caused confusion in the results.
  In order to eliminate this interference, Kirshwink’s experiment was carried out in a so-called “Faraday cage” (a thin aluminum box). It is a space made of two floors, and electromagnetic background noise is shielded by coils.
  In the “cage”, people sit quietly, with only pure magnetic fields, no interference, and no other stimuli. Next, Kirshwink applied a rotating magnetic field similar in strength to the earth, and observed whether there were any activities (reactions or changes) in the brains of these people-these activities were monitored in real time by EEG (electroencephalogram) monitors.
  He observed that when the magnetic field rotates counterclockwise, the participant’s alpha wave drops. Kirshwink explained that this suppression of alpha waves is related to brain activity, and it shows that a group of neurons are activated in response to changes in the “magnetic field” (the only variable in the experiment). In fact, the neural response is delayed by a few hundred milliseconds-which proves that the brain is active.
  He also observed that when the direction of the magnetic field was twisted to the floor, a similar response appeared; but not when the magnetic field was twisted upwards or rotated clockwise. He said that this may reflect the polarity of the “magnetic compass” in our body.
  Many researchers are repeating Kirshwink’s experiment to further verify its results. Once the results are the same, then the “fact” that humans have a “sixth sense” will be further confirmed.
