Il cervello umano è unisex, ovvero non esistono due categorie distinte, femminile e maschile. Lo ha rivelato uno studio condotto presso l'università di Tel Aviv e pubblicato sulla rivista PNAS.
Gli esperti hanno analizzato le risonanze magnetiche del cervello di oltre 1'400 persone appartenenti a entrambi i sessi, concludendo che non esiste un vero e proprio diformismo sessuale dello stesso. Vi sarebbero solo delle piccole differenze legate al sesso riscontrate in un limitato gruppo di regioni neurali.
I risultati della ricerca hanno fatto emergere che il cervello di ciascun individuo è sempre un mosaico unico di caratteristiche, alcune più comuni nelle femmine che nei maschi o viceversa, e solo nell'8% dei casi esaminati è apparso del tutto maschile (tutte le regioni sessualmente dimorfiche si presentano in versione maschile) oppure femminile (tutte le regioni sessualmente dimorfiche si presentano in versione femminile).
