This text presents a contemporary statement of what is known about morphological development of the normal and abnormal human nervous system and puts into perspective the continued importance of changes that occur in the course of foetal development and how these processes may become defective. The book should prove useful on a daily basis to all neuropathologists, general pathologists, and child neurologists as a short review of normal and disturbed brain development. The complexity of the central nervous system (CNS) structures overlaps with the differing times and rates of maturation of those structures. This results in variations in the times of the background of normal and pathologic processes occurring in the CNS over the long term, which extends over the course of several years, but is evident until three years of age, when the changes demonstrating brain maturation are visible by means of light microscopy. The book should also be useful to researchers working in these fields as well as students of human neuroembryology and developmental neuropathology.
