Il y a quelques mois, ils avaient mis au jour une victime de l&rsquo;\u00e9ruption du V\u00e9suve, en l&rsquo;an 79, sur le site arch\u00e9ologique d&rsquo;Herculanum. En raison de la chaleur extr\u00eame, les analyses montraient qu&rsquo;une partie du cerveau de la victime avait \u00e9t\u00e9 transform\u00e9e en verre. Mais les d\u00e9couvertes ne s&rsquo;arr\u00eatent pas l\u00e0. Comme ils le r\u00e9v\u00e8lent dans une nouvelle \u00e9tude publi\u00e9e dans la revue PLOS ONE, les scientifiques affirment qu&rsquo;ils ont trouv\u00e9 des neurones dans ledit cerveau, des neurones vieilles de pr\u00e8s de 2 000 ans.<\/p>\n<p>Gr\u00e2ce \u00e0 la microscopie \u00e9lectronique \u00e0 balayage (SEM) et \u00e0 des outils de traitement d&rsquo;image avanc\u00e9s, Pier Paolo Petrone, anthropologue l\u00e9giste \u00e0 l&rsquo;Universit\u00e9 Federico II de Naples, et son \u00e9quipe ont r\u00e9ussi pour la premi\u00e8re fois \u00e0 montrer des cellules neuronales parfaitement pr\u00e9serv\u00e9es dans les restes vitrifi\u00e9s du cerveau et de la moelle \u00e9pini\u00e8re. \u00ab\u00a0La d\u00e9couverte de tissus c\u00e9r\u00e9braux dans d&rsquo;anciens restes humains est un \u00e9v\u00e9nement inhabituel, explique Pier Paolo Petrone dans un communiqu\u00e9. Mais ce qui est extr\u00eamement rare est la pr\u00e9servation int\u00e9grale des structures neuronales d&rsquo;un syst\u00e8me nerveux central vieux de 2 000 ans, dans notre cas avec une r\u00e9solution sans pr\u00e9c\u00e9dent.\u00a0\u00bb<\/p>\n<p>La rapidit\u00e9 avec laquelle l&rsquo;\u00e9ruption du V\u00e9suve a d\u00e9vast\u00e9 la r\u00e9gion a permis la conservation de vestiges biologiques en les vitrifiant. \u00ab\u00a0La d\u00e9couverte extraordinaire de structures neuronales anciennes parfaitement pr\u00e9serv\u00e9es a \u00e9t\u00e9 induite par la conversion de tissus humains en verre, ce qui indique le refroidissement rapide des nuages \u200b\u200bde cendres volcaniques chaudes qui ont frapp\u00e9 Herculanum au d\u00e9but de l&rsquo;\u00e9ruption\u00a0\u00bb, explique Guido Giordano, volcanologue \u00e0 l&rsquo;Universit\u00e9 de Roma Tre dans un communiqu\u00e9.
