The presence of magnetic nanoparticles in the human brain were first discovered in 1992. But no one knows where they came from and what effect they provide.
A recent study indicates that these particles come from the high temperature environment, which suggests that they are not the products of an odd function in the human body. Their shape indicated that they might be derived from the results of industrialization, rather than from biological sources.

Professor Barbara Maher of the University of Lancaster used a sample of 37 people who had lived in Mexico City or Manchester, England. By combining the analysis of magnetic and electron microscopy to study the magnetic particles on the brain, she found that there're two different types with different origins as well.

However, in the Proceedings of the National Academy of Sciences, Maher reported that others have the same type of magnetite nanosfer formed by combustion. In particular, some of the particles appear to have come together and are difficult to explain the absence of high temperatures.

Magnetite (Fe3O4) is one of the natural substances. In the absence of that, people will never understand the relationship of electricity. And those magnetic particles play a role in many animals, especially the most famous is the pigeon, which used by them to sense magnetic fields.
Maher herself came to the conclusion that the production of magnetic particles with diameters less than 20 nanometers that goes into the brain is the result of industrial activities. Once in the brain, these particles will produce chemicals known as reactive oxygen associated with Alzheimer's disease. *** [EKA | FROM VARIOUS SOURCES | IFLSCIENCE]
