Book Description
The book is devoted to the main discussion of the nervous system. Whether information about nerve details is connected to each other, or whether it is distributed along single nerve fibers and reaches with great accuracy. The generally accepted model is the neuron theory of Ramon y Cajal. His opponent is the histologist Camillo Golgi. According to the theory of Ramon y Cajal, nerve impulses propagate in one direction with the help of chemical synapses. According to the Golgi theory, nerve stimuli are connected to each other and innervate the organs in batches. Connections occur between fibers with the help of electrical synapses and syncytia. Impulses are able to propagate in different directions. The monograph presents a large number of preparations of neuronists, which are evidence of the opposite reticular theory. A technique is presented that makes it possible to unmask the illustrations of Ramon y Cajal and demonstrate a large number of syncytia on his preparations. The same amount is found in the tangled networks of the gastrointestinal tract ("abdominal brain"). Electrical connections have also been established in other parts of the nervous system. Electrophysiologically, a circular interconnection of electrical synapses, spikes in a circle has been established, and multiple variants of feedback of nerve fibers have been identified. The unified neural and reticular theories are unified.

Book Description
At the crossroads of art and science, Beautiful Brain presents Nobel Laureate Santiago Ramón y Cajal’s contributions to neuroscience through his groundbreaking artistic brain imagery. Santiago Ramón y Cajal (1852–1934) was the father of modern neuroscience and an exceptional artist. He devoted his life to the anatomy of the brain, the body’s most complex and mysterious organ. His superhuman feats of visualization, based on fanatically precise techniques and countless hours at the microscope, resulted in some of the most remarkable illustrations in the history of science. Beautiful Brain presents a selection of his exquisite drawings of brain cells, brain regions, and neural circuits with accessible descriptive commentary. These drawings are explored from multiple perspectives: Larry W. Swanson describes Cajal’s contributions to neuroscience; Lyndel King and Eric Himmel explore his artistic roots and achievement; Eric A. Newman provides commentary on the drawings; and Janet M. Dubinsky describes contemporary neuroscience imaging techniques. This book is the companion to a traveling exhibition opening at the Weisman Art Museum in Minneapolis in February 2017, marking the first time that many of these works, which are housed at the Instituto Cajal in Madrid, have been seen outside of Spain. Beautiful Brain showcases Cajal’s contributions to neuroscience, explores his artistic roots and achievement, and looks at his work in relation to contemporary neuroscience imaging, appealing to general readers and professionals alike.

Book Description
This collection contains hundreds of beautiful rarely-seen-before figures produced throughout the nineteenth century and the beginning of the twentieth century by famed father-of-modern-neuroscience Santiago Ramón y Cajal (1852-1934) and his contemporaries. Cajal was captivated by the beautiful shapes of the cells of the nervous system. He and his fellow scientists saw neurons as trees and glial cells as bushes. Given their high density and arrangement, neurons and glial resembled a thick forest, a seemingly impenetrable terrain of interacting cells mediating cognition and behavior.

Book Description
The author makes a unique contribution to the field by discussing the history and philosophy of the neurosciences, and then developing critical approaches which integrate techniques, theory, and ethics. Taken as a whole, Jacobson's work will provide a coherent and humane framework for future research programs. The paperback edition of this highly successful text, first published in 1993, is now available! The author brings the ethics of neuroscience into a closer relationship with empirical research. Covering the field's history, philosophy, theories, and techniques, this volume provides the necessary moral and ethical framework to evaluate neuroscience research.

Book Description
The question of how nerves communicate with one another was the subject of a heated & protracted dispute between pharmacologists & neurophysiologists. This book recalls the debate & how the theory of chemical transmission was eventually confirmed by the discovery of neurotransmitters.

Book Description
Epilepsy is a devastating group of neurological disorders characterized by periodic and unpredictable seizure activity in the brain. There is a critical need for new drugs and approaches given than at least one-third of all epilepsy patients are not made free of seizures by existing medications and become "medically refractory". Much of epilepsy research has focused on neuronal therapeutic targets, but current antiepileptic drugs often cause severe cognitive, developmental, and behavioral side effects. Recent findings indicate a critical contribution of astrocytes, star-shaped glial cells in the brain, to neuronal and network excitability and seizure activity. Furthermore, many important cellular and molecular changes occur in astrocytes in epileptic tissue in both humans and animal models of epilepsy. The goal of Astrocytes and Epilepsy is to comprehensively review exciting findings linking changes in astrocytes to functional changes responsible for epilepsy for the first time in book format. These insights into astrocyte contribution to seizure susceptibility indicate that astrocytes may represent an important new therapeutic target in the control of epilepsy. Astrocytes and Epilepsy includes background explanatory text on astrocyte morphology and physiology, epilepsy models and syndromes, and evidence from both human tissue studies and animal models linking functional changes in astrocytes to epilepsy. Beautifully labelled diagrams are presented and relevant figures from the literature are reproduced to elucidate key findings and concepts in this rapidly emerging field. Astrocytes and Epilepsy is written for neuroscientists, epilepsy researchers, astrocyte investigators as well as neurologists and other specialists caring for patients with epilepsy. Presents the first comprehensive book to synthesize historical and recent research on astrocytes and epilepsy into one coherent volume Provides a great resource on the field of astrocyte biology and astrocyte-neuron interactions Details potential therapeutic targets, including chapters on gap junctions, water and potassium channels, glutamate and adenosine metabolism, and inflammation

Book Description
The life of Camillo Golgi was an extraordinary intellectual adventure in three major fields of biology and medicine, namely neuroscience, emerging cell biology, and the new science of medical microbiology. in 1873, Golgi published the description of a revolutionary histological technique which allowed one, for the first time, to visualize a single nerve cell with all its ramifications, and which could be followed and analyzed even at a great distance from the cell bodies. The so-called "black reaction" (later named the "Golgi method") provided the spark to a truly scientific revolution which allowed the morphology and the basic architecture of the cerebral tissue to be evidenced in all its complexity, thus contributing to the foundation of modern neuroscience. It has been written that, in the same way Galileo Galilei was able to find new stars observing any sky region with his telescope. Golgi was able to find new nervous structures and nerve cells by applying his black reaction to any brain region. Finally, the details of the most complex structure in the known universe, the brain, could be characterized. Golgi's black reaction is just one of his many successes and contributions to society. As this book illustrates, he has also strongly contributed to the development of cell biology with the "internal reticular apparatus" (later called the "Golgi apparatus") and to medical microbiology with his studies on malaria. Engrossing and authoritative, Golgi: A Biography of the Founder of Modern Neuroscience, is a detailed account of one of the most prominent European researchers of his time.
