2022 The Human Brain during the First Trimester 3.5- to 4.5-mm Crown-Rump Lengths (pdf)

This first of 15 short atlases reimagines the classic 5-volume Atlas of Human Central Nervous System Development. This volume presents serial sections from specimens between 3.5 mm and 4.5 mm with detailed annotations, together with 3D reconstructions. An introduction summarizes human CNS development by using high-resolution photos of methacrylate-embedded rat embryos at a similar stage of development as the human specimens in this volume. The accompanying Glossary gives definitions for all the terms used in this volume and all the others in the Atlas.
