The new concept challenges the accepted theory that has been widely shared for about 200 years since K. von Baer (1828, 1837) and K. von Kupffer (1906) who proposed that three primary brain vesicles at earlier developmental stages

General Rules of Brain Morphogenesis in Vertebrates: An Hourglass Model, Baer’s theory concerning the presence of the three primary brain vesicles has no universality throughout vertebrates. The results rather indicate that the early brain morphogenesis is diverse among vertebrates. In brain development, the earliest morphological feature shared by the brains of all mem
