Cortical Spreading Depression of Leao


Book Description

This book focuses on energy metabolism and brain functions related to Cortical Spreading Depression of Leao (CSD), an important issue in brain pathophysiology. The first part of the book offers a comprehensive overview of the history and early research on CSD, and then discusses the recent advances in the technology used to map and monitor brain mitochondrial NADH redox state and other physiological functions during CSD. The chapters explore the connection between CSD and mitochondrial function under hypoxia, Ischemia and various drugs treatment, and provide a resource to scientists researching the development of CSD during various brain pathophysiological conditions. This book is essential to scientists and students working in the field of bioenergetics of the brain and various organs and tissues in the body. The use of this technology is also crucial and applicable in the neuroscience field.







Updating in Headache


Book Description

In September 1983 the First International Headache Congress took place, the founding congress of the International Headache Society (lHS). This meeting was attended by around 200 headache specialists from some 20 countries. One of the principal goals of the IHS, which was formed in London in 1982, is to promote and stimulate interest and research in the headache field. In addition to the sponsorship of continued-education events, this also involves the coordination of scientific pro jects and the organization of future conferences. There is no doubt that headaches represent an everyday problem in medical practice. When the first headache clinics were established some years ago, they were regarded as very progressive. Today there are special outpatient centers and clinics for headache patients. However, this specialization has certainly not progressed very far. The fact is that differential diagnosis and treatment of recurrent and chron ic headaches represents a broad field that cuts across many disciplines. Headaches are thus relevant not only to the neurologist, but also to the psychiatrist, the neuro surgeon, the internist, the endocrinologist, the psychologist, the pharmacologist, and the biochemist. Despite intensive research in numerous and very disparate medical disciplines there are still no generally accepted pathophysiologic concepts for many headache syndromes. Realizing the importance of a multidisciplinary fo rum, the IHS assumed the organization of this congress in collaboration with the German Migraine Society.




Brain Slices in Basic and Clinical Research


Book Description

Brain Slices in Basic and Clinical Research describes advancements in the field of brain function and dysfunction through use of central nervous system slice preparations. Topics are authored by leading scientists and include the following: Mechanisms of synaptic plasticity as the basis of memory processes Chaos and synaptic variability Brain calcium currents Glutamate receptors Pathophysiology of excitotoxins Cerebral hypoxia-ischemia Neuronal injury Free radicals Optical methods of measuring brain metabolism Voltammetry in brain slices Calcium imaging Patch-clamp recording and application of macromolecules through patch-clamp pipettes in brain slices Intracellular double labeling of various neuronal populations Use of brain slices in teaching neurophysiological methods Most of the topics are published in book format for the first time, and some of the techniques are more fully detailed than in any other book.




Cellular Membrane


Book Description

Cellular Membrane: A Key to Disease Processes focuses on cellular membranes as a key to unlocking important new information about the pathological processes of strokes, heart attacks, diabetes, cancer, and other major diseases. The clinical relevance of basic research is particularly emphasized. Topics include calcium ions and calcium channel blockers, membrane ion channels and diabetes, membrane perturbation by asbestos fibers and disease, membrane receptors and signal transduction in tumor cells, anti-HIV compounds with membrane oriented specificity, and neuroleptic malignant syndrome. Cellular Membrane: A Key to Disease Processes is filled with illustrations, schemes, exciting ideas, and provocative hypotheses that are bound to lead to the development of new pharmacological techniques. It will prove to be an excellent reference guide for cell biologists and pathologists.




Biomag 96


Book Description

A modified Linear Estimation Approach was performed to reconstruct current sources within the heart. Based on MRI data sets the Boundary Element Method was used to create tailored multicompartment models of the human thorax which were used to solve the forward problem of magnetocardiography. The ability of the proposed method was demonstrated for the localization of a single current dipole as an example of a focal source. By means of introducing small shiftings to all reconstruction dipoles during linear estimation solution as well as performing a successive focussing strategy ignoring places without significant electrical activity the method could easily be extended to the reconstruction of real 3D sources. Based on a special minimum-norm solution the source volume can be estimated applying a finite element approximation using cube elements. The size of an extended current source can be estimated by superimposing the reconstructed dipoles to an equivalent dipole and comparing the corresponding volume with the sphere which would be related to the equivalent dipole. The deviation of these volumes can be taken as a criterion for non-dipolarity of sources.




Neural and Brain Modeling


Book Description

Neural and Brain Modeling reviews models used to study neural interactions. The book also discusses 54 computer programs that simulate the dynamics of neurons and neuronal networks to illustrate between unit and systemic levels of nervous system functions. The models of neural and brain operations are composed of three sections: models of generic mechanisms; models of specific neuronal systems; and models of generic operations, networks, and systems. The text discusses the computational problems related to galvanizing a neuronal population though an activity in the multifiber input system. The investigator can use a computer technique to simulate multiple interacting neuronal populations. For example, he can investigate the case of a single local region that contains two populations of neurons: namely, a parent population of excitatory cells, and a second set of inhibitory neurons. Computer simulation models predict the various dynamic activity occurring in the complicated structure and physiology of neuronal systems. Computer models can be used in "top-down" brain/mind research where the systemic, global, and emergent properties of nervous systems are generated. The book is recommended for behavioral scientists, psychiatrists, psychologists, computer programmers, students, and professors in human behavior.
