Book Synopsis Magnetic Resonance Spectroscopy and Imaging in Neurochemistry by : Herman Bachelard
Download or read book Magnetic Resonance Spectroscopy and Imaging in Neurochemistry written by Herman Bachelard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advances in Neurochemistry series was initiated for a readership of neuroscientists with a background in biochemistry. True to this concept, the present volume brings together various applications of magnetic resonance technology to advance our knowledge of how the nervous system functions. Whether at the cellular, tissue slice, or intact organism level. magnetic resonance techniques are by their nature noninvasive, and thus provide a window through which biochemical reactions can be viewed without grinding, binding, or other wise perturbing ongoing physiological processes. As technological improve ments in methodology, such as higher and more uniform magnetic fields, novel paradigms for data analysis, etc. , are made, we find increased sensitivity and improved temporal and spatial resolution for functional imaging techniques on the one hand, and better separation of signals that identify chemical properties in spectral shift studies, on the other. It is upon knowledge such as is described in the twelve chapters that follow, that further advances in scientific discovery and the biomedical applications of tomorrow will be based. We are grateful to Dr. Bachelard, the Volume Editor, and to the authors of the individual chapters for their efforts. We also note that with this volume Dr. Morris Aprison, a co-founder of the Advances in Neurochemistry series has stepped down and acknowledge with thanks his major role in its inception. In addition, we thank our past and present Advisory Editors. Bernard W.

This book was released on 2006-08-25 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: In summarizing current insights and controversies over concussions in athletics, this book makes the vital point that symptom resolution does not necessarily mean injury resolution. Research shows that dysfunctional pathways continue for extended periods even after a minor concussion. Until the consequences of short-term perturbations and long-term residual brain dysfunctions are better understood, concussions must be treated with respect and given a higher priority for continued research activity.

Abstract: As compared with other imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI) provides distinctive advantages with better contrast and resolution in imaging brain anatomy and function in vivo. As compared with electrophysiological and histological tracing techniques, MRI enables longitudinal investigation with higher efficiency, lower labor cost and less possibility of sampling error. The major objective of this doctoral work is to utilize cellular and molecular MRI to investigate normal brain functions and injuries in vivo. The results successfully demonstrated MRI as an efficient and sensitive tool for providing comprehensive assessment of brain injuries for promoting accurate prognosis and timely intervention, and for studying fundamental questions with regard to cortical adaptations to challenges in the young adulthood. Firstly, diffusion tensor imaging (DTI) and T2-weighted imaging were employed to characterize longitudinal neuronal and axonal changes of pyramidal tract (PY), a critical part of corticospinal tract, following experimental intracerebral hemorrhage (ICH). Combining DTI with T2-weighted imaging results, ipsilateral PY injuries following ICH were diagnosed as four stages. Quantitative analysis revealed transient diffusivity decreases in PY both contralateral and ipsilateral to the primary hemorrhagic site. Evolution of the ipsilateral DTI parameters correlated with histological findings and indicated evolving and complex pathological processes underlying monotonic FA decrease. These results demonstrated multi-parametric DTI as a valuable imaging tool for non-invasive and longitudinal monitoring of secondary PY injuries. Secondly, DTI and manganese-enhanced MRI (MEMRI) were utilized to detect neuronal changes of substantia nigra (SN) following experimental ICH in rodents. DTI revealed early changes in SN both contralateral and ipsilateral to the primary hemorrhagic site. Evolution of the ipsilateral parameters correlated with the histological results. MEMRI provided insights into the cellular phenotype changes at the late stage. DTI can serve as a valuable imaging tool for non-invasive early detection and longitudinal monitoring of secondary SN injuries, while MEMRI could complementally provide information regarding the late stage inflammation process. Multi-parametric MRI could facilitate clinical and preclinical investigations of SN injuries for exploring disease mechanisms and developing new therapeutic strategies. Thirdly, MEMRI was performed to characterize the interhemispheric interactions in normal and monocularly deprived rodent visual brain. Characteristic transcallosal manganese labeling was observed in the normal group in a manner consistent with previous histological findings. Significant decrease of such labeling was observed in rats with left or right eyelid suturing, or with left eye enucleation, but not in rats with right eye enucleation. These results demonstrated MEMRI as an efficient tool for investigating interhemispheric interactions both anatomically and functionally. These results also indicated that the adult brain recruits different mechanisms for its adaptations to eyelid suturing and enucleation, thus shedding light on our understanding of the transcallosal interhemispheric excitation and inhibition. Lastly, new paradigms other than pressure injection for intracortical manganese administrat

This book was released on 2003 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research is oriented towards understanding the reading, language, and articulation deficits associated with Neurofibromatosis Type 1 (NF-1) and relating these deficits to the underlying pathophysiology of NF-1 as revealed by Magnetic Resonance Spectroscopy Imaging (MRSI). A second goal is to determine how differences in activation, as measured by functional Magnetic Resonance Imaging (FMRI), are linked to the cognitive/academic impairments associated with NF-1. A third goal is to further understand how T-2 weighted hyperintensities on Magnetic Resonance Imaging (MRI) scans are related to cognitive/academic impairments associated with NF-1. Each aim addresses the research in terms of pathophysiology and how cognitive/academic functioning of children with NF-1 compares to control groups when examined in both genetic (i.e., sibling) as well as general population (both reading disabled and non-reading disabled) contexts. We hypothesize that abnormalities of NAA, Choline, or their ratios, will exists in the thalamusandwill correlate with language, reading, and articulation deficits in NF-1, defined by "lowering" of the cognitive scores of each child with NF-1 relative to his/her unaffected sibling. For the second goal, we hypothesize that children with NF-1 will activate their brains similarly to reading disabled children during FMRI tasks. For the third goal, we hypothesize that reading, language, and articulation deficits will correlate with the number of brain locations with T2-weighted hyperintesities. Thus, neuroimaging permits the pursuit of furthering our understanding of how the NF-1 gene affects the brain in terms of basic neurobiologic factors (ultrastructural, physiological, and localization) as well as their impacts on cognition (reading, language, and articulation) in NF-1.

This book was released on 2012-12-06 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed dramatic advances in the development and use of magnetic resonance imaging (MRI) techniques that can provide quantitative measures with some degree of pathological specificity for the heterogeneous substrates of multiple sclerosis (MS). Magnetic resonance spectroscopy (MRS) is one of the most promising of these techniques. Thanks to MRS, axonal damage is no longer considered an end-stage phenomenon typical of only the most destructive lesions and the most unfortunate cases, but rather as a major component of the MS pathology of lesions and normal-appearing white matter at all the phases of the disease. This new concept is rapidly changing our understanding of MS pathophysiology and, as a consequence, the therapeutic strategies to modify the disease course favorably. Many of the authors have pionereed the use of MRS in MS, thus contributing to the foundation of the "axonal hypothesis".
