The Human Brain During the Early First Trimester (Atlas of Human Central Nervous System Development Book 5)

This is the fifth and last Volume in the Atlas of Human Central Nervous System Development Series. It deals with human brain development during the early first trimester from the third through the seventh gestational weeks. Serial sections from 14 specimens are illustrated and annotated in detail, together with 3?D reconstructions of the brains of eight specimens. The Human Brain During the Early First Trimester focuses on these major themes:Growth of the stockbuilding neural progenitor cells along the expanding shorelines of the superventricles Identification of the mosaic compartments of the neuroepithelium that generate neurons and neuroglia for different brain structures Onset of neurogenesis and expansion of a newly identified meningeal tissue, the superarachnoid reticulum, which provides space for the growing brain parenchyma Migratory paths of neurons in the early-maturing regions of the brain and the formation of the earliest fiber tracts Finally, a concluding essay with illustrations and graphs summarizes the major events of human CNS development. It also provides a theoretical account of the morphogenetic processes involved in human CNS development and relates them to current genetic and molecular research in animal models.This atlas is also available as part of a five volume set. The first volume in this series presents illustrations of structural development and includes clearly labeled photographs and extensive quantitative comparisons. Overview plates, unabbreviated terms, animal experimental data, glossary of terms, and 3D color images are also included. The second volume of this atlas focuses on the development of the human brain during the third trimester, and features grayscale photographs of sections of the brains cut in three cardinal plane planes of normal specimens from gestational week 26-37. The third volulme provides a pictorial record of the maturning brain at low and high magnification, accompanied by a structural analysis based on animal experiments Fifth in the "Atlas of Human Central Nervous System Development" series, this book provides a survey of the complex structural processes that occur during development. It includes both high resolution black and white photographs as well as ghost image photographs with unabbreviated labels
