Scientists have found preserved brain cells from a young man who died during the infamous eruption of Mount Vesuvius in AD 79. The structure of brain cells is still clearly visible in a black glassy substance found in his skull, the researchers said. Scientists have been trying to determine whether the glassy material is part of the man’s brain, and the discovery of cell structure confirms this judgment. < / P > < p > as for how the glassy substance is produced, the researchers believe that his brain’s transition to glassy texture is due to extreme heating and rapid cooling. Pier Paolo PETRONE, the lead author of the study, said the results showed that vitrification took place in herculanim and froze the neuronal structure of the victim and preserved it intact to this day. < p > < p > herculanim is an ancient town at the foot of Vesuvius volcano, which erupted nearly 2000 years ago. Pompeii is the most famous victim of volcanic eruption, but the hydrothermal flow that took most of the victims attacked hekulannim first. The huge and hot ash cloud was extremely hot, and materials such as flesh and wood were carbonized in an instant. < / P > < p > in rare cases, the preserved organic material appears to include the brain, the researchers said. The glass was found in the cracked and charred skull of the man, who is believed to be around 20 years old. He was found lying face down on the bed. < / P > < p > the electron microscope is used to observe the smallest details in the sample. The researchers found tiny spherical structures and long tubular structures that look like projections of neurons and their so-called axons. These structures are very small, only 550 to 830 nanometers, and the researchers say they are too small to be capillaries. These spherical structures seem to retain the membrane and the filaments or structural proteins in the cell. These samples were also studied by energy dispersive X-ray spectrometry. Using the technology, scientists discovered a protein called atp6vif, which is known to be involved in the transport of chemicals called neurotransmitters.
