The fourth volume in the Atlas of Human Central Nervous System Development series, The Human Brain During the Late First Trimester provides new information about features of the perinatal brain. With no other atlas available on the development of the human brain during the late first trimester, this volume fills a large void in the current literature. Easy to use, it contains photographs of the entire brain arranged in companion plates that include two parts: a large, high resolution black and white photograph and a "ghost image" of the photograph with unabbreviated labels. It is a user-friendly survey of the complex structural processes that occur during human CNS development.
