| homology_notes |
The early development of most vertebrate brains is similar (...). The zebrafish neural tube follows the same basic differentiation pattern as the mammalian neural tube (reference 1); The brain develops from three embryonic enlargements of the neural tube, which later differentiate into five regions. A forebrain differentiates into telencephalon and diencephalon. The midbrain, or mesencephalon, remains undivided. The hindbrain divides into the metencephalon and myelencephalon. Cavities within the brain enlarge to form a series of interconnected ventricles (reference 2).[well established][VHOG] |

the terms metencephalon and myelencephalon are only meaningful in mammals and birds - Neuroanatomy of the Zebrafish Brain. Note that its not clear if this refers to the developing medulla oblongata - MA (adult) has two distinct classes |
