An anecdotal guide for the perplexed new investigator as well as a refreshing resource for the old pro, covering everything from valuable personality traits for an investigator to social factors conducive to scientific work. Santiago Ramon y Cajal was a mythic figure in science. Hailed as the father of modern anatomy and neurobiology, he was largely responsible for the modern conception of the brain. His groundbreaking works were New Ideas on the Structure of the Nervous System and Histology of the Nervous System in Man and Vertebrates. In addition to leaving a legacy of unparalleled scientific research, Cajal sought to educate the novice scientist about how science was done and how he thought it should be done. This recently rediscovered classic, first published in 1897, is an anecdotal guide for the perplexed new investigator as well as a refreshing resource for the old pro. Cajal was a pragmatist, aware of the pitfalls of being too idealistic-and he had a sense of humor, particularly evident in his diagnoses of various stereotypes of eccentric scientists. The book covers everything from valuable personality traits for an investigator to social factors conducive to scientific work.

This book provides current information about the three areas mentioned in the title: Neuronal Migration and Development, Degenerative Brain Diseases, and Neural Plasticity and Regeneration. The chapters about brain development examine the cellular and molecular mechanisms by which neurons are generated from the ventricular zone in the forebrain and migrate to their destinations in the cerebral cortext. This description of cortical development also includes a discussions of the Cajal-Retzius cell. Another chapter provides insight about the development of another forebrain region, the hypothalamus. The remaining chapters of this section examine the clinical relevance of brain development in certain disease states in humans: neural tube defects and the normal and abnormal development of human electroencephalographic recordings during the first year of age.
The second section on degenerative disorders of the brain begins wtih details about the dopaminergic neurons in the substantia niger and their loss in Parkinson's disease. Two subsequent chapters describe changes in brain aging, including changes in the numbers of myelinated axons. Other chapters in this section describe important cellular and molecular changes found in Alzheimer's disease and human epilepsy. Together, these chapters summarize much of our current knowledge about the major molecular and cellular changes found in several degenerative diseases of the brain.
The last section addresses the issues of brain plasticity and regeneration in the adult brain and begins with a chapter on how the brain's own stem cells provide newly generated neurons to the hippocampal dentate gyrus and how these neurons become integrated into neural circuitry. The following two chapters examine some of the neuroplastic changes that take place in motor and sensory cortices of awake behaving primates. The concluding two chapters address the issue of regeneration in the injured spinal cord and the factors that may contribute to its success.

Now in its second edition, Brain Architecture is the continued exploration of how the brain works. At the very core of our existence, the brain generates our thoughts and feelings, directs our voluntary interactions with the environment, and coordinates all of the vital functions within the body itself. This long-overdue new edition explains this oftentimes daunting intricacy and exquisite detail. The first half of the book discusses the basic parts and how they work, presenting an overview of the nervous system at both the microscopic and macroscopic levels. The approach follows three classic lines of thought that proceed from simple to complex: the history of neuroscience research, the evolution of the nervous system, and the embryological development of the vertebrate central and peripheral nervous systems. The second half of the book outlines the basic wiring diagram of the brain and nervous system-how the parts are interconnected and how they control behavior and the internal state of the body. This is done within the framework of a new four-system network model that greatly simplifies understanding the structure-function organization of the nervous system. Written in clear and sparkling prose, beautifully illustrated, and thoroughly updated, Brain Architecture, Second Edition is must-read for anyone interested in the science of how the brain works.
