This is the first English-language publication of the complete works of the great Spanish neurohistologist, Santiago Ramon y Cajal, on the cerebral cortex. The new translations include all Cajal's very early contributions on the cortex of small mammals, relevant chapters from his definitive textbook, and all his great works on the human cerebral cortex made at the peak of his career. The book also presents Cajal's surveys of cortical structure dating from his later years. It is extensively annotated, and the editors have verified and completed all Cajal's references. Special introductory chapters review the state of knowledge during each period covered, and the work concludes with an extensive essay on modern cortical neurohistology in which the quality and lasting significance of Cajal's contributions are highlighted.
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.
When Santiago Ramón y Cajal started to unravel the fine structure of the nervous system in the last decades of the XIXth century maybe only his unbeatable soul of brave Spaniard imagined that most of the descriptions were scientific truths that lasted to date. Simple histological stainings, curiosity to ameliorate these, monocular microscopes, patience for drawing his observations and a rich imaginative open mind: this is the recipy for Cajal success. His descriptions of connectivity in the nervous system, compiled in Cajal's opus magna published in 1904 ("Textura del sistema nervioso del hombre y los vertebrados") and 1911 ("Histologie du systeme nerveux"), have been corroborated by modern techniques decade after decade. Even more, the main hypothesis that Cajal raised are universally recognised as biological laws, today: the neuron theory, the law on the dynamic polarization of the neuron and the chemotropic hypothesis. That is: the nervous system is not a sincitial network but is formed by individual cells; the transmission of the nerve impulses follow a main direction within a given neuron; the axons are guided by chemical substances in a chemotropic way, till form synapses with their targets. Attracted by Cajal's strong personality and scientific success, a number of medical students and doctors join him in the crusade to explore the nervous system. And the seed planted by the universal savant was really successful: Francisco Tello described interesting aspects of the regeneration of peripheral nerves which are very useful for neuroscientist currently working in this topic; Nicolás Achúcarro significantly contributed to study neuroglia and future microglia; Pío del Río-Hortega identified two out of the four main nervous cell types, the oligodendrocytes and microglia, and proposed an almost still valid classification for the CNS tumours; Fernando de Castro made was the first description of arterial chemoreceptors in the carotid body; Rafael Lorente de Nó was a dominant figure of Neuroscience for decades after the IInd World War, first describing the columnar organization of the cerebral cortex well before Mountcastle, Hubbel and Wiesel. Even less recognised co-workers and disciples of Cajal (his brother Pedro Ramón y Cajal, Domingo Sánchez, the neurologist Rodríguez-Lafora... protagonised discoveries that are consolidated scientific truths today). Altogether, it is difficult (if not impossible) to find a school in biology contributing in such a fundamental and variated way to the common acervo like the collectively known as Cajal School or Spanish Neurological School. Although the particular way to work of the Maestro, selecting a pleiade of brilliant collaborators with whom accomplish such a titanic feat, giving them freedom for their studies, has been recognised and confronted to antagonic systems followed by other relevant scientists and scientific schools, the general recognition of such a significant major milestones for Neuroscience and their vigency in the well-marched XXIst century is not: this is the purpose of this Ebook, to remind all these examples of how successful can be the scientific work when it is minutious, constant and performed by brilliant, imaginative and skilled scientists with a minimal conditions supporting their efforts.
The works and thoughts of Santiago Ramn y Cajal in a faithful rendition of the original Spanish version, with additional facts contained in the French translation, both of which are currently quoted around 200 times each year in the scientific literature. This is the only authorized English translation and makes use of uniform nomenclature according to contemporary scientific English. Most of the illustrations are reproductions of Cajal's original art work, with cross references to the figure numbers of the Spanish and French versions, while the taxonomic glossary uses current scientific names, and their colloquial English counterparts.
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.
This book is a reprint of an English translation of Cajal's original work, with abundant notes and commentaries by the editor. This text describes Cajal's fundamental contributions to neuroscience, which continue to be important today. It accurately details Cajal's ideas and data, and providesreaders with the opportunity to learn what Cajal thought about his research career and the significance of his observations. Excerpts from Tello's memorial lectures also provide a contemporary view of Cajal's work.
This book contains a large collection of beautiful figures produced throughout the nineteenth century and the beginning of the twentieth century and that represent some characteristic examples of the early days of research in neuroscience. The main aim of this work is to demonstrate to the general public that the study of the nervous system is not only important for the many obvious reasons related to brain function in both health and disease, but also for the unexpected natural beauty that it beholds. This beauty has been discovered thanks to the techniques used to visualize the microscopic structure of the brain, a true forest of colourful and florid neural cells. As illustrated by his marvellous drawings, the studies of Santiago Ramon y Cajal (1852-1934) no doubt contributed more than those of any other researcher at the time to the growth of modern neuroscience. Thus, we have honored his name in the title of this book, even though the figures contained in the main body of the book are from 91 authors. Looking at the illustrations in this book the readers will not only marvel at Cajal's drawings but they will also find that many of the other early researchers that studied the nervous system were also true artists, of considerable talent and aesthetic sensibility. Thus, the present book contains numerous drawings of some of the most important pioneers in neuroscience, including Deiters, Kolliker, Meynert, Ranvier, Golgi, Retzius, Nissl, Dogiel, Alzheimer, del Rio-Hortega and de Castro. The colourful period: internal structure and chemistry of the cells. This book will be of general interest, not only due to the captivating aesthetic appeal of the illustrations but also because they represent the bases of our current understanding of the nervous system.
