Durante la cuarta semana, después del cierre de los neuroporos, el extremo cefálico del tubo neural craneal al cuarto par de somitos se dilata considerablemente y aparecen las tres vesículas encefálicas primarias a partir de las cuales se origina el encéfalo: Prosencéfalo (cerebro anterior), mesencéfalo (cerebro medio) y rombencéfalo (cerebro posterior). [...] El mesencéfalo constituye la vesícula encefálica inmediatamente cefálica al rombencéfalo que sufre menos modificaciones durante el desarrollo del SNC [sistema nervioso central]. La cavidad de la vesícula mesencefálica se reduce considerablemente para formar un conducto que unirá los futuros III y IV ventrículos: el acueducto cerebral (de Silvio). 1, record 2, Spanish, - mesenc%C3%A9falo
