Can humans feel magnetic fields?

The magnetic fieldaffecting the body and the human mind resembles super strength, have X-Men in science fiction films, but researchers believe that some people actually are able to sense our planet’s magnetic field. Many animals, from pigeons to the turtles, use this perception for navigation, while cattle, according to previously conducted research, prefers to combine with the field being in him. For many years among the scientific community continued to debate as to whether the people of this instinct. The results, published in the journal eNeuro, say so.

We are part of the magnetic of the Earth’s biosphere

As writes The Guardian, we, as a species, have not lost a magnetic sensory system, which our ancestors had millions of years ago. According to Professor Joseph Kirshvink, research Director of the California Institute of technology, people are a part of the magnetic of the Earth’s biosphere. In their work Kirschvink and his colleagues from the US and Japan describe that the discovery was made after the construction of hexagonal cells, the walls of which were made of aluminium to protect the unit from electromagnetic interference. These walls also contained coils through which currents are passed, creating a magnetic field approximately the same strength as that of the Earth.

Each participant was asked to enter in a dark cage and sit on the wooden chair, face to the North. During the experiment, the team measured the brain waves of the subjects using electroencephalogram (EEG). In some experiments created the magnetic field was fixed in one direction, while others rotate. In other cases, the magnetic field is not created β€” it meant that participants were exposed to only the natural magnetic field of the Earth. Moreover, subjects did not know what experiment was conducted.

The results obtained from 34 adult subjects, showed that certain scenarios of the experiment caused a drop of alpha brainwaves. Alpha waves arise when we close our eyes and begin to relax. When increasing the functional activity of the brain amplitude of the alpha rhythm decreases up to complete disappearance. Falling brainwaves occurred, if an artificial magnetic field was directed northward, and then deployed up or down, or pointing down when you hover to the North and rotated clockwise. As people in the Northern hemisphere, nodding your head or turning your head to the right.

According to the researchers, the results akin to what the brain is “crazy” for reacting to a sudden change of environment. This means that a person is able to detect such changes β€”the responses of the subjects vary greatly. According to the team, new research suggests that the human system of magnetoreception distinguishes North from South, supporting anmechanism that includes a special cells containing crystals of iron-based. It is believed that these crystals rotate, like a compass needle, opening or closing pores in the cells, thereby affecting the signals sent to the brain.
