Proved: some people may feel a change in the magnetic field

Many representatives of the animal world, includingSome species of birds, sea turtles, and also some species of bacteria have a special “navigation system” that allows them to feel and use the Earth’s magnetic field as a compass. This ability is called magnetoreception. About her scientists have learned in the early 70s. Since the 90s, experiments have been conducted aimed at finding the same features in humans. However, to find evidence of this ability then failed. Technologies and methods of analysis have since received significant development, so today an international group of researchers decided to conduct a new experiment with people, looking at the question from a new point of view. The results of the work of researchers are described in the journal eNeuro.

It turned out that some people reallyable to feel the magnetic field. And as the study, which was conducted a year earlier, shows, people can do it, probably through magnetic particles (magnetite) scattered around the entire brain area.

"Scientists first witnessed a clear reactionto change the magnetic field in humans. Even if the magnetic field itself was not physically sensed by man, the brain signals observed by scientists demonstrated a clear response in changing the intensity of the magnetic field, ”comments the results of the study by Michael Wincklhofer, a biologist from the University of Oldenburg named after Karl von Ossetsky, who did not participate in this study.

In order to find out whether people can feelmagnetic field, scientists invited 34 adult volunteers to take part in the new experiment. They were asked to sit in a dark test chamber, in which there were large square magnetic coils. Running current through these coils, scientists changed the intensity and orientation of the magnetic field in the chamber.

While participants were at the request of scientists inrelaxed and eyes closed, the researchers manipulated the magnetic field around them. To monitor changes in brain activity (alpha waves), each participant was subjected to an electroencephalogram (EEG) during the experiment.

It turned out that when changing the magnetic fieldthe amplitude of brain activity varies in the alpha range - from 8 to 13 hertz. The experiment showed that among 34 participants, four had a very strong reaction to one change in the orientation of the magnetic field: a shift from northeast to northwest. This shift will be the same as that of a person outside the camera, as if he quickly turned his head from left to right, but considering that the head moves through a static magnetic field, and not a field moving around it.

Also, the other four people observedreduced alpha brain wave activity in amplitude by as much as 60 percent. But they reacted only when the field shifted from the northeast to the northwest, and not to the other side.

Researchers can not explain the reasonthis phenomenon. But according to one of the assumptions, this may be due to some unique feature similar to the one according to which some people are right-handed and some are left-handed.

In addition, it is noted that some of the participantsExperiment there was a strong reaction to the tilt of the field, which in real conditions would be a reaction to your journey between the northern and southern hemispheres of the planet.

To eliminate randomness receivedresults in the first experiment, the researchers conducted repeated experiments on the same voluntary a few weeks later. It is reported that the results were the same, which only adds to the credibility of the study.

According to the researchers themselves, who conductedThese experiments, they do not consider these results as a discovery. Most people are not able to feel the magnetic field, because each person's brain is unique, which is confirmed and manifested, for example, in our abilities. For example, some people are well versed in art, others in mathematics. In other words, human organs should not behave and react in the same way.

Experts also believe that distant ancestorshumans had the ability to feel the magnetic field, but in the course of evolution this ability lost its relevance. However, some of its remains are still preserved by some people, even if they no longer use it in their daily lives.
