The British University of Oxford published on March 20 research that is a mystery about what happens to our body after death, our veins, marrows and remains of organs become dust or not; In principle yes, but that does not always happen and there is a case that intrigues scientists and that is the strange resistance of the brain to turning into dust.

To try to answer this mystery, a group of researchers from the University of Oxford in the United Kingdom led by postgraduate researcher Alexandra Morton-Hayward carried out the largest study to date of the global archaeological literature on human brains, they have managed to compile an archive that multiplies by 20 the number of brains that were in the previous records, in total they have gathered files of more than 4,000 belonging to more than 200 different places, on six continents.

The oldest ones are 12,000 years old, their origin is very diverse, there are brains that belonged to people from the Egyptian and Korean culture, through British and Danish monks, to Arctic explorers and victims of war, the places where they have been found They are also of a bewildering variety, the shores of a lake in Stone Age Sweden, the depths of an Iranian salt mine 2,500 years ago or the Summit of the Andes at the time of the height of the Inca empire.

A file was made for each brain where all the available data was analyzed, from historical climatic data to the geology of the place where it was found. The intention was to have an idea about how this extraordinary conservation was possible. It seems that factors such as the dehydration, that is, the organ dries out, freezing, saponification, which is the transformation of the body's fats into the so-called grave wax, and tanning, which is generally produced with peat, which is how the mummies of the animals are formed. swamps.

This does not explain the strange preservation of the brains, only at the beginning of the investigation of a disconcerting mystery and this term is not used by me, the researchers use it because the researchers remember that in the forensic field it is well known that the brain is one of the first organs to decompose after death and yet there are these 4000 extraordinary cases and surely there are still more that remain to be discovered.

Of those analyzed by the researchers, there are about 1,300 that are even stranger, since they are the only soft organs that have been preserved, that is, there were the bones and the brain, this is something really strange and has raised questions about what it is like. that the brain can resist destruction when the other organs disappear and wait because there are more.

Curiously, these brains that survived the rest of the organs also represent the oldest in the archive and there are several that date back to the last ice age. The conservation mechanism of the oldest remains a complete enigma, although the team of scientists is considering some hypotheses such as the possible intervention of metals in the conservation process, but the research is only in its beginnings.

Once we know how they have been preserved, perhaps we could address another question: we could one day reveal the information they may contain.
