Book Synopsis Lesion-Induced Neuronal Plasticity in Sensorimotor Systems by : H. Flohr
Download or read book Lesion-Induced Neuronal Plasticity in Sensorimotor Systems written by H. Flohr and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sensorimotor systems are not rigidly wired predetermined networks but rather highly plastic structures that learn and modify their entire performance in response to changes in external or internal conditions. Lesions or distortions of the system's input, which initially cause a functional disorganization, induce an active reorganization which often leads to a recovery of function. Examples of lesion-induced neural plasticity have been known for some hundred years; however, an awareness of their value as research tools is relatively new. This current interest is a consequence of rapid ly changing ideas concerning the nature of CNS organization. Out of these, concepts are emerging which describe neural nets as modifiable, highly dynamic, self-organizing structures. This trend is clearly reflected in this volume, which contains the proceedings of a symposium held in Bremen in July 1980 as a satellite meeting of the XXVIIIth International Congress of Physiological Sciences. The first part of this conference was devoted to some gen eral aspects of plasticity, discussing the current theories of functional recovery as well as morphological, neurochemical, physiological, molecular, and ontogenetic aspects. The second part dealt with lesion induced plasticity in specific sensorimotor systems of the spinal cord, brain stem, and cerebral cortex.
Book Synopsis Post-Lesion Neural Plasticity by : Hans Flohr
Download or read book Post-Lesion Neural Plasticity written by Hans Flohr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural networks are not rigidly wired but rather highly plastic structures, the functional architecture of which can be actively reorganized in response to external or internal events. Lesions of such networks induce plastic processes which in time may lead to a recovery of the initially disrupted function. This type of neural plasticity is the main focus of the book, which presents a broad spectrum of experimental paradigms for lesion-induced plasticity as in the spinal cord, the vestibular, oculomotor, visual and olfactory system, the cerebellum and the cerebral cortex, including recent methodological developments. Concepts and perspectives in understanding neural plasticity are reported in reviews and original research reports and are thoroughly discussed.

Book Synopsis Neuronal Plasticity: Building a Bridge from the Laboratory to the Clinic by : Jordan Grafman
Download or read book Neuronal Plasticity: Building a Bridge from the Laboratory to the Clinic written by Jordan Grafman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last twenty years there has been an explosive growth in our understanding of the molecular, cellular, and anatomical changes that occur in the days and weeks following brain injury. It is now clear that training and exposure to certain environments can modify and shape neuronal plasticity in lower animals and humans. In humans, in particular, there are new ways of charting neuronal plasticity at the ensemble or regional level using functional neuroimaging techniques such as positron emission tomography and functional magnetic resonance imaging. Thus, the time seems right for transporting the laboratory results to the clinic so that experimental findings can be tested in the "field". This volume provides some impetus to moving the field of cognitive neuroscience a little further in its efforts to improve the lives of patients who have suffered a debilitating brain injury.
Book Synopsis Plasticity in the Human Nervous System by : Simon Boniface
Download or read book Plasticity in the Human Nervous System written by Simon Boniface and published by Cambridge University Press. This book was released on 2009-06-25 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well known that the functional organisation of the cerebral cortex is plastic and that changes in organisation occur throughout life in response to normal and abnormal experience. Transcranial magnetic stimulation (TMS) is a non-invasive and painless technique that has opened up completely new and fascinating avenues to study neural plasticity. First, TMS can be used to detect changes in excitability or connectivity of the stimulated cortex which may have occurred through processes such as learning or recovery from a lesion. Second, repeated TMS by itself can induce changes in excitability and connectivity of the stimulated cortex which may be used therapeutically in neurological and psychiatric disease. Third, TMS can induce short-lasting 'virtual lesions', which may directly test the functional relevance of brain plasticity. Current knowledge of all these exciting possibilities is brought together in this book, written by the world's leading experts in the field. The book is an essential compendium on plasticity of the human brain for clinical neurophysiologists, neurologists, psychiatrists and neuroscientists.
Book Synopsis Training-induced Plasticity in Resting-state Sensory and Motor Networks by : Shahabeddin Vahdat
Download or read book Training-induced Plasticity in Resting-state Sensory and Motor Networks written by Shahabeddin Vahdat and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Research on plasticity in motor systems has for the most part developed separately from work on sensory plasticity, as if training-induced changes to the brain affected each of these systems in isolation. The aim of this thesis is to explore the association between the sensory and motor systems when a new skill is acquired. The experiments reported in this dissertation systematically examine two hypotheses about neuroplasticity: (i) that motor learning changes perceptual function and the function of somatosensory areas of the brain, and (ii) that somatosensory training changes both motor function and motor areas of the brain. The first study aimed at providing a unified approach to test the first hypothesis. We combined both psychophysical and neuroimaging procedures to examine the connection between changes in the behavior and brain as a result of motor learning. We used a dynamics adaptation task as a model of motor learning in conjunction with somatosensory discrimination of the limb's movement direction which permits quantification of perceptual changes that occurs in conjunction with motor learning. We used functional magnetic resonance imaging (fMRI) to calculate measures of functional connectivity during resting-state periods following learning. This technique allowed us to study longer lasting plasticity in the sensorimotor system, during the period in which the motor memory is being consolidated. We developed a new hypothesis-driven technique which enables us to incorporate psychophysical measures in functional connectivity analysis to identify behaviorally-related neuroplasticity as a result of learning. Using this technique, we identified a new network in motor learning involving second somatosensory cortex, ventral premotor cortex and supplementary motor area whose activation is specifically related to perceptual changes that occur in conjunction with motor learning. Subjects who showed greater change in functional connectivity within this network, also showed a greater change in perceptual function. In study two, we proposed and implemented a new analytic data-driven method based on independent component analysis (ICA), which enabled us to systematically extract and classify shared and condition-specific networks corresponding to the pre-learning and post-learning conditions. The proposed algorithm was specifically designed to solve the problems of the regular ICA approach in conducting between-condition comparisons. Using this method we identified a specific network corresponding to the post-learning condition comprising clusters in contralateral superior parietal lobule, second somatosensory cortex, premotor cortex, and supplementary motor area. The third study was aimed at testing the second hypothesis described above. Using similar procedures and techniques to those used in the first study, we found that somatosensory discrimination training combined with periods of passive movement as short as 45 minutes increased functional connectivity between sensory and motor areas of the brain and, importantly, in motor areas alone. In behavioral terms, somatosensory training facilitates motor learning. Improvements were seen in both the rate and extent of learning and they persisted for at least one day. Sensory repetition without perceptual learning was less able to induce plasticity in the motor system. This suggests that somatosensory training can induce reorganization in the motor system and benefits from cognitive involvement and skill acquisition in the sensory domain. Overall, our studies point to a unified model of sensorimotor plasticity in which the effects of learning are not local to either sensory or motor systems, but rather each has effects that spread into functionally related areas of the brain beyond the base modality." --
Book Synopsis Neuroplasticity and Rehabilitation by : Sarah A. Raskin
Download or read book Neuroplasticity and Rehabilitation written by Sarah A. Raskin and published by Guilford Press. This book was released on 2011-08-08 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain plasticity is the focus of a growing body of research with significant implications for neurorehabilitation. This state-of-the-art volume explores ways in which brain-injured individuals may be helped not only to compensate for their loss of cognitive abilities, but also possibly to restore those abilities. Expert contributors examine the extent to which damaged cortical regions can actually recover and resume previous functions, as well as how intact regions are recruited to take on tasks once mediated by the damaged region. Evidence-based rehabilitation approaches are reviewed for a range of impairments and clinical populations, including both children and adults.

This book was released on 2012-12-06 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: 5) To what extent do events occurring during regeneration re semble those seen in development? Questions like these remain open, particularly in relation to the mammalian central nervous system and to the effects of lesions or disease. The first chapters of this volume are concerned primarily with normal and abnormal development of the nervous system. New concepts have emerged over the past few years as a result of experiments made on the development of the higher nervous system in mammals. Thus, the principles of cell death, competition, selective retraction of specific processes, and the effects of abnormalities on the development of the rest of the system have now been extensively investigated. In addition, considerable information is available about biochemical changes during normal and abnormal development in the human. At the other end of the scale, in invertebrates it is now possible to follow cell lineage and to define the origin and fate of a sin gle neuron of known function together with its processes. While an understanding of development is clearly important for studying basic mechanisms of repair and regeneration, one cannot expect the processes to be identical or even comparable in the two situations. For example, cell migration, guidance by radial glial fibers, selective cell death, and the critical periods for competition, sprouting, and retraction observed in the visual system can hardly playa part in repair.
