The Human Brain during the First Trimester 3.5- to 4.5-mm Crown-Rump Lengths

1) Classic anatomical atlases

2) Detailed labelling of the earliest phases of prenatal neurological development without abbreviations

3) Appeals to neuroanatomists, developmental biologists and clinical practioners

4) Persistent relevance - brain development is not going to change, but this Atlas offers updated terminology for primordial neural structures.
