The brain was so well preserved 2600 years ago that scientists speculated that an unknown substance had been produced

A 2600 year old corpse whose brain is intact. Although many scientists didn’t believe it at first, the fact is just around the corner.

This kind of brain, known as “Herrington brain”, is one of the best preserved specimens of ancient human nerve tissue in the world.

However, this confuses scientists because, in general, shortly after a person’s death, brain tissue begins to decompose faster than muscles and internal organs, and the brain should first become dust.

But in unusual circumstances, hesselton’s brain is a special case. According to the carbon dating results, hesselton’s brain last breathed oxygen between 673 and 482 BC, which may have been cut off by a sharp knife and thrown into the mud in the iron age.

After more than a year of patient research, scientists say they may have discovered the long-term secrets of hesrendton’s brain. Microscopically, the results show that there are similarities and differences between the brain of hayslington and that of ordinary brain.

After further analysis of specific antibody markers, it was found that the number of neural structures belonging to “helper” cells in the brain was out of proportion, which was different from the normal brain. Many scientists know that if soft tissues are dried, frozen or stored in an oxygen free acidic environment, they can usually be preserved for thousands of years. Strangely enough, ancient humans had such preservation technology thousands of years ago.

What surprised scientists most was that other tissues, such as scalp and hair, were corroded, but only the brain survived. Scientists also found that hesselton’s brain is very hard, about 80% of the mass of an adult brain.

In order to reveal the secret of hesselton’s brain invariance, scientists patiently studied the slow decomposition process of protein in modern neural tissue samples in the past year and compared it with the internal decay process of hesselton’s brain.

The results of the study led scientists to speculate that the brain can produce an unknown chemical that can destroy destructive enzymes within a few months after death. This chemical makes proteins form stable aggregates and persist at higher temperatures.

Proteases in the ancient brain may have been inhibited by an unknown compound that diffuses from the outside of the brain to deeper structures. That means there’s nothing special about this 2600 year old brain, but it makes chemicals that make it coagulate and stronger.
