Nolte's The Human Brain

Turtles can walk around for hours with no oxygen supply to their brains. In contrast, our brains are absolutely dependent on a continuous supply of well-oxygenated blood. After just 10 seconds of brain ischemia, we lose consciousness. After 20 seconds,…

The cavity of the embryonic neural tube develops into a continuous, fluid-filled system of ventricles lined with ependymal cells; each division of the central nervous system (CNS) contains a portion of this ventricular system. Cerebrospinal fluid (CSF) is formed within…

Living brain is soft and mushy, despite the network of cytoskeletal proteins contained in neurons and glial cells. Without support of some kind, the central nervous system (CNS) would be unable to maintain its shape, particularly as we walk and…

The human central nervous system (CNS) is composed of the brain and spinal cord. This chapter briefly discusses the major surface and internal structures of the brain (summarized in Fig. 3.26 ) and, together with the following six chapters, lays…

As complex as the human nervous system is, it starts out embryonically as a simple, tubular, ectodermal structure. An understanding of the development of the nervous system helps make sense of its adult configuration and organization. Similarly, congenital malformations of…

The aims of this book are to present and explain some basic anatomical facts about how the brain is put together, to discuss aspects of how it works, and to present clinical features to aid in application and retention. This…
