Experiments confirming the person's ability to sense changes in the magnetic field

It is known that the ability to sense the magnetic field (magnetoreception) have many living organisms. These primarily include the migratory species of birds and fish, using the "built-in compass" for routing. In recent years, the ability to magnetoreception found in lobsters, snails, worms, newts and frogs. They have this ability and the representatives of the cat family.

With the evidence base in relation to mammals is more complex, but nevertheless, there is every reason to believe that it is present in them. For example, the mole rats and wild mouse nests place, guided by the direction of the earth's magnetic field, and deer and cows on pasture are placed along his body. The presence of a person's ability to magnetoreception until recently called into question. Nevertheless, research and search for analogies with the animal world did not stop here June 23 at Science magazine published an article «Maverick scientist thinks he has discovered a magnetic sixth sense in humans», telling about the work of Joe Kirschvinka (Joe Kirschvink) of California Institute of technology, who conducted a series of experiments, came to the conclusion that there is a human physiological mechanism responsible for the ability to sense the direction and changing magnetic fields. Prior to the publication of the results of the study, the researchers reported in April 2016 at a conference at the Royal Institute of Navigation, London.

Taking into account the specific conditions and the purity was carried out in the last one from the university laboratory experiment located on the two floors below ground level: a volunteer went into the room with a magnetic screen, the walls of which were covered with a layer of aluminum (Faraday cage). There is also a system of three mutually perpendicular rectangular spaced coils (Merritt system), creating a uniform magnetic field passing through the center of the window. Thanks to this arrangement the magnetic field fails to flexibly change by changing the amount of current in the coils. Brain response to possible magnetic field is recorded using electroencephalography (EEG) for changing the alpha waves recorded by EEG can judge the specifics occurring in the cerebral cortex changes.

A series of eight tests performed for an hour in the automatic mode: in some cases the magnetic field, the approximate absolute value of the earth field, slowly revolved around the subject's head, the other person has impacted only the natural geomagnetic field. Tests alternated at random and carried out in complete darkness, so that neither the experimenter nor the subject knew which of the tests carried out at the moment.

It was found that when the magnetic field is rotated counterclockwise, the alpha waves are weakened sharply. The same thing happened with the deviation of the magnetic field down. Explanations for why alpha waves react to changes in a magnetic field oriented in that direction, and do not react to changes if the field is directed oppositely, is found, but it is likely it may be indicative of the polarity of our "magnetic compass . »

Conclusion: By itself, an alternating magnetic field can influence the brain electrical currents that might mimic the EEG signal, but a direct effect would be displayed immediately and recorded. In this case, in principle, and it is especially emphasizes Joe Kirschvink that nervous reaction was delayed for a few hundred milliseconds - this delay might occur because of the active brain reaction, that is, if there is indeed worked a magnetically analyzer
<. br> So far, the collected statistics is based on experiments involving just 20 people, but, nevertheless, as the author of the experiment, in all cases, he was able to achieve a stable repeatability. Of course, even systematically repeated tests on the background a little bit poor statistics can not yet form the basis of expanded scientific articles with a reasonable evidence base, but Kirschvink sure that very soon he will be able to fill the required information gap.
