Download or read book Molecular Origins of Brain and Body Geometry written by Antonio Lima-de-Faria and published by Springer. This book was released on 2014-10-07 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: New concepts arise in science when apparently unrelated fields of knowledge are put together in a coherent way. The recent results in molecular biology allow to explain the emergence of body patterns in animals that before could not be understood by zoologists. There are no ”fancy curiosities” in nature. Every pattern is a product of a molecular cascade originating in genes and a living organism arises from the collaboration of these genes with the outer physical environment. Tropical fishes are as startling in their colors and geometric circles as peacocks. Tortoises are covered with the most regular triangles, squares and concentric circles that can be green, brown or yellow. Parallel scarlet bands are placed side by side of black ones along the body of snakes. Zebras and giraffes have patterns which are lessons in geometry, with their transversal and longitudinal stripes, their circles and other geometric figures. Monkeys, like the mandrills, have a spectacularly colored face scarlet nose with blue parallel flanges and yellow beard. All this geometry turns out to be highly molecular. The genes are many and have been DNA sequenced. Besides they not only deal with the coloration of the body but with the development of the brain and the embryonic process. A precise scenario of molecular events unravels in the vertebrates. It may seem far-fetched, but the search for the origin of this geometry made it mandatory to study the evolution of matter and the origin of the brain. It turned out that matter from its onset is pervaded by geometry and that the brain is also a prisoner of this ordered construction. Moreover, the brain is capable of altering the body geometry and the geometry of the environment changes the brain. Nothing spectacular occurred when the brain arrived in evolution. Not only it came after the eye, which had already established itself long ago, but it had a modest origin. It started from sensory cells on the skin that later aggregated into clusters of neurons that formed ganglia. It also became evident that pigment cells, that decide the establishment of the body pattern, originate from the same cell population as neurons (the neural crest cells). This is a most revealing result because it throws light on the power that the brain has to rapidly redirect the coloration of the body and to change its pattern. Recent experiments demonstrate how the brain changes the body geometry at will and within seconds, an event that could be hardly conceived earlier. Moreover, this change is not accidental it is related to the surrounding environment and is also used as a mating strategy. Chameleons know how to do it as well as flat fishes and octopuses. No one would have dared to think that the brain had its own geometry. How could the external geometry of solids or other figures of our environment be apprehended by neurons if these had no architecture of their own? Astonishing was that the so called ”simple cells”, in the neurons of the primary visual cortex, responded to a bar of light with an axis of orientation that corresponded to the axis of the cell’s receptive field. We tend to consider our brain a reliable organ. But how reliable is it? From the beginning the brain is obliged to transform reality. Brain imagery involves: form, color, motion and sleep. Unintentionally these results led to unexpected philosophical implications. Plato’s pivotal concept that ”forms” exist independently of the material world is reversed. Atoms have been considered to be imaginary for 2,000 years but at present they can be photographed, one by one, with electron microscopes. The reason why geometry has led the way in this inquiry is due to the fact that where there is geometry there is utter simplicity coupled to rigorous order that underlies the phenomenon where it is recognized. Order allows variation but imposes at the same time a canalization that is patent in what we call evolution.

Download or read book Astrocytes in Patho Physiology of the Nervous System written by Vladimir Parpura and published by Springer Science & Business Media. This book was released on 2008-12-11 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrocytes were the original neuroglia that Ramón y Cajal visualized in 1913 using a gold sublimate stain. This stain targeted intermediate filaments that we now know consist mainly of glial fibrillary acidic protein, a protein used today as an astrocytic marker. Cajal described the morphological diversity of these cells with some ast- cytes surrounding neurons, while the others are intimately associated with vasculature. We start the book by discussing the heterogeneity of astrocytes using contemporary tools and by calling into question the assumption by classical neuroscience that neurons and glia are derived from distinct pools of progenitor cells. Astrocytes have long been neglected as active participants in intercellular communication and information processing in the central nervous system, in part due to their lack of electrical excitability. The follow up chapters review the “nuts and bolts” of ast- cytic physiology; astrocytes possess a diverse assortment of ion channels, neu- transmitter receptors, and transport mechanisms that enable the astrocytes to respond to many of the same signals that act on neurons. Since astrocytes can detect chemical transmitters that are released from neurons and can release their own extracellular signals there is an increasing awareness that they play physiological roles in regulating neuronal activity and synaptic transmission. In addition to these physiological roles, it is becoming increasingly recognized that astrocytes play critical roles during pathophysiological states of the nervous system; these states include gliomas, Alexander disease, and epilepsy to mention a few.

Download or read book The Apallic Syndrome written by G. Dalle Ore and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of the apallic syndrome is one which has long been familiar to me, although I have not personally studied it as deeply as I would have wished. I became acquainted with this syndrome long before the last war, when my neurosurgical colleague Hugh Cairns (1952), made his pioneer contribution under the term "akinetic mutism" . This was an ar resting title, but it was one which did not altogether satisfy some of his colleagues, includ ing myself. We found it difficult to suggest an alternative. That is one reason why I wel come the expression "apallic syndrome" . Forensic practice has forced me from time to time to consider rather more deeply this distressing syndrome, and to try and marshal my ideas in a form which would satisfy my colleagues in the legal profession. More than once I have been instructed to make a medico legal assessment of these unfortunate patients. The points which have concerned my lawyer friends have not been matters of diagnosis, or of morbid anatomy, or of etiology. The fac tual problem which has been put before me was to make some approximate assessment as to the expectation of life. Vague guess-work is unacceptable in such circumstances. What the lawyers require is a precise and dogmatic answer.
Download or read book How the Brain Evolved Language written by Donald Loritz and published by Oxford University Press. This book was released on 2002-02-28 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can an infinite number of sentences be generated from one human mind? How did language evolve in apes? In this book Donald Loritz addresses these and other fundamental and vexing questions about language, cognition, and the human brain. He starts by tracing how evolution and natural adaptation selected certain features of the brain to perform communication functions, then shows how those features developed into designs for human language. The result -- what Loritz calls an adaptive grammar -- gives a unified explanation of language in the brain and contradicts directly (and controversially) the theory of innateness proposed by, among others, Chomsky and Pinker.
Download or read book The olivo cerebellar system written by Egidio D'Angelo and published by Frontiers Media SA. This book was released on 2016-04-29 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades, investigations on the olivo-cerebellar system have attained a high level of sophistication, which led to redefinitions of several structural and functional properties of neurons, synapses, connections and circuits. Research has expanded and deepened in so many directions and so many theories and models have been proposed that an ensemble review of the matter is now needed. Yet, hot topics remain open and scientific discussion is very lively at several fronts. One major question, here as well as in other major brain circuits, is how single neurons and synaptic properties emerge at the network level and contribute to behavioural regulation via neuronal plasticity. Other major aspects that this Research Topic covers and discusses include the development and circuit organization of the olivo-cerebellar network, the established and recent theories of learning and motor control, and the emerging role of the cerebellum in cognitive processing. By touching on such varied and encompassing subjects, this Frontiers Special Topic aims to highlight the state of the art and stimulate future research. We hope that this unique collection of high-quality articles from experts in the field will provide scientists with a powerful basis of knowledge and inspiration to enucleate the major issues deserving further attention.
Download or read book Development of the Cerebellum from Molecular Aspects to Diseases written by Hassan Marzban and published by Springer. This book was released on 2017-07-27 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present the most current and cutting-edge knowledge regarding the molecular basis of cerebellar development, focusing on information relevant to laboratory scientists and clinicians providing service to patients with cerebellar disorders. Knowledge obtained from advanced neuroimaging techniques that are used during development, and from molecular- and genetic-based studies has provided rapidly-growing evidence that the cerebellum is a brain region that is highly impacted by developmental defects. Cerebellar defects result in significant intellectual and motor function impairment that affects both the patients and their families.
