On April 17, 1955, 76-year-old Albert Einstein was admitted to Princeton Hospital with a complaint of heart pain, and the next morning the great physicist died of massive hemorrhage after a ruptured aortic aneurysm. Many scientists were haunted by the genius of Albert Einstein, and therefore, 7 hours after the death of the outstanding physicist, a command was given to extract the brain for research. This was done by the pathologist Thomas Harvey, who injected a 10% formalin solution through the internal carotid artery, removed the brain and subsequently stored it in a 10% formalin solution. Harvey photographed the brain from various angles and then sliced it into approximately 240 blocks. He packed the obtained segments into a colloidal film.
The story turned out to be rather strange, since the scientist did not give any documentary consent to the extraction of the brain, and the relatives agreed to this after the fact. The pathologist himself vaguely explained that Eingtein gave his consent, to whom he gave and when ... it is not clear.
Scientific research has shown that the areas of Einstein's brain responsible for speech and language are reduced, while the areas responsible for processing numerical and spatial information are enlarged.
The first scientific study of Einstein's brain was carried out by Mariana Diamond, Amold Szheibel, Green Murphy, and Thomas Harvey and was published in the journal Experimental Neurology in 1984. Scientists have confirmed that the number of glial cells in Einstein is higher than the average level, but the exact number of neurons and neuroglial cells was not counted, but their ratios were given instead, which raised the importance of the study into question.
The second scientific work was published in 1996. According to her, Einstein's brain weighs one kilogram two hundred and thirty grams, which is less than the average weight of a human brain at this age - one kilogram four hundred grams.
Another study was published in the medical journal The Lancet in June 1999. The scientist's brain was compared to brain samples from people whose average age was 57 years. Areas of the scientist's brain were identified that are large and are responsible for the ability to mathematics. It also found that Einstein's brain is 15 percent wider than average. It was also interesting that none of the many diseases of the elderly Einstein, it seems, did not affect the health of his brain.
Over the years, sections of Einstein's brain have been sent for study to researchers around the world, but unfortunately, at the moment, no one has been able to find the key to his genius.
