The term Encephalon refers to the embryonic precursor to the brain and the retina as defined by dissection of the embryo of vertebrates, including mammals. It is composed of the Prosencephalon (sum of Telencephalon and Diencephalon), the Mesencephalon and the Rhombencephalon, embryonic precursors of the forebrain, midbrain and hindbrain respectively.
     Latin terms are frequently used as synonyms of the English terms. However, some primary structures of the mature brain originally believed to originate from one subdivision of the Encephalon have subsequently been found to originate from another. Thus, the classical organization of the mature brain and of the Encephalon differ in some respects. For that reason, in NeuroNames we shall eventually use the Latin term as the standard name for subdivisions of the embryonic nervous system that are precursors to a somewhat different combination of mature structures than the combination classically represented by the English term. Use of the term 'Encephalon' to represent the embryonic precursor of the mature brain and retina is a good example.
