When Mount Vesuvius extravasate in the year 79 , the volcano unleashed an avalanche of throttle and rock hot enough to boil rake , vaporize flesh and even transform mo of genius tissue into Methedrine , agree to a new study .
Archaeologistsrarely unveil man brainsduring their dig , and if they do , the organs find max - like and smooth . During a operation call in saponification , triglyceride in the fatty brain tissue react with charged particles in the surrounding environment , transforming into soap over clock time . Scientists found something very different , however , when they examined the remains of a military personnel who croak in Herculaneum during the Vesuvius volcanic eruption .
Fragment of glassy black material extracted from the cranial cavity of a victim of the volcanic eruption at Herculaneum in the year 79.
Enveloped in a surge of hot ash , the dupe ’s brain had been burn to twisted shameful minute through a appendage called vitrification . The glassy material " encrusted " the aerofoil of the man ’s skull , accord to a report issue Jan. 22 in theThe New England Journal of Medicine .
The strange discovery was made by Dr. Pier Paolo Petrone , a prof of human osteobiology and forensic anthropology at the Federico II University Hospital in Naples , Italy . Inprevious work , Petrone and his colleagues examined the skeletal remains of more than 300 people in Herculaneum who had fled to boathouses during the Vesuvius eruption , only to conk out from the extreme heat of the volcanic blast .
Herculaneum lie down about 11 mile ( 20 kilometers ) from Pompeii , also famously swallow by the eruption , and sit nigher to the base of Vesuvius . This proximity to thevolcanoensured that mass in Herculaneum meet a especially gruesome fortune : Steam rent off by their boiling ancestry generated intense insistence in their skull , causing their headway to explode .

In their Modern study , Petrone and his carbon monoxide - source examined a Vesuvius victim who had die not on the waterfront , but on a wooden bed in a edifice sleep with as the Collegium Augustalium . The corpse was find in the 1960s , buried within a mound of volcanic ash . Like the boathouse victims , the charred skeleton bears the sparse remnant of a skull that burst during the eruption .
The squad spotted shards of glassy black fabric lodged within oddment of the exploded skull and scatter among the remains of the cranial cavity . atomic number 27 - writer Piero Pucci of the Centro di Ingegneria Genetica - Biotecnologie Avanzate in Naples take the fragment ofbrain tissueand analyzed the protein found within .
The analysis revealed protein known to be found in different areas of the human brain , including the crisp cerebral cortex , responsible for in high spirits brain functions like decisiveness - qualification ; the amygdala , important to emotional processing ; and the substantia nigra , which helps control movement and our response to reward . Pucci also spot fatty acids typically find in human hair filth , along with triglycerides unremarkably find in wit tissue sample .
