L'anatomia di ogni cervello umano è unica, tanto quanto le impronte digitali. Lo dimostra uno studio di un gruppo di ricercatori dell'Università di Zurigo che si è occupato di analizzare le caratteristiche genetiche degli esseri umani mettendole in relazione con l'esperienza di vita.
Che l'esperienza lasci tracce nel cervello è una cosa risaputa, ma anche gli eventi di breve durata non sono da sottovalutare. Il gruppo, guidato dal neuropsicologo Lutz Jäncke, ha analizzato durante due anni i cervelli di 191 persone tra i 64 e gli 85 anni. Attraverso delle risonanze magnetiche sono riusciti a studiarne 450 caratteristiche neuroanatomiche.
Gli scienziati sono stati in grado di identificare per ogni individuo una combinazione unica di queste caratteristiche. Secondo il professor Jäncke, questi risultati evidenziano i grandi progressi realizzati attraverso le analisi con risonanza magnetica.
