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神经 发表于 2025-3-27 15:35:54

Subdivisions of Neural Tube Along the Dorsoventral Axis,l rods and the earliest neural tubes of medaka embryos, by visualizing expression patterns of several developmental genes. These dorsal and ventral subdivisions of the teleost neural tube differ not only functionally, but also in the context of brain evolution. There exists a wide variety in the extcarotid-bruit 发表于 2025-3-28 00:23:09

The rostral structures, such as the telencephalon and optic vesicles, rotate ventralward during this period. The transverse subdivisions of the medaka前面 发表于 2025-3-28 02:47:45
