Atlas of Brain Mapping by Konrad Maurer,Thomas Dierks Pdf

From its discovery in 1929 by Hans Berger until the late 1960s, when sensory visual and auditory evoked potentials were dis covered and became popular, the EEG was the most important method of neurophysiological examination. W-ith the advent of computer technology in the 1980s, it became possible to plot the potential fields of the EEG onto models of the scalp. This plot ting of information as neuroimages followed the structural and functional techniques of Cf, MRI, PET and SPECf. The success of this method, which began in the early 1980s, has led to the brain mapping of EEGs and EPs being increasingly used for di agnosistic purposes in neurology, psychiatry and psychopharma cology. The pioneers of this method believed in it and were commit ted to its success. However, many traditionalists felt that it gave no new information and so regarded the method with scepticism. Some found both the coloured maps and the mapping technique misleading, which led to unnecessary conflict between mappers and their chromophobic oponents. Emotions have run so high that some professional bodies have justifiably adopted guidelines and warned of the misuse of the method.

Topographic Brain Mapping of EEG and Evoked Potentials by Konrad Maurer Pdf

Imaging procedures have been used for many years and are becoming increasingly important in a number of medical disciplines. This is due to recent technological advances, primarily computerization. The meth ods employed in CNS diagnostics are collectively referred to as "neu roimaging" and include procedures for investigating both cerebral morphology and cerebral function, such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomogra phy (PET), and single-photon emission computed tomography (SPECT). Topographic mapping of electroencephalograms (EEG) and evoked potentials represents one of the functional procedures and per mits topographic imaging of EEG, evoked potentials, and magnetic fields. The latter application includes not only magnetic fields evoked by stimuli relating to different sensory modalities, but also endogenous and motor fields resulting from spontaneous brain magnetic activity, as recorded by magnetoencephalograms (MEG), the magnetic comple ment of the EEG. The advantage of recording electric and magnetic fields over other neuroimaging procedures is that these techniques are completely noninvasive and have extremely short analysis times (in the millisecond range). The aim of this book is to clarify the current state of this emerging technology, to assess its potential for substantive contributions to brain research, to delineate areas for further research and, over all, to envis age clinical applications in disciplines such as psychiatry, neurology, and neuropsychology.

Introduction to Brain Topography by Peter K.H. Wong Pdf

It had been difficult to find appropriate teaching material for students and newcomers to this field of brain electromagnetic topography. In part, this is due to the many disciplines involved, requiring some knowledge of the physical sciences, mathematics, neurophysiology and anatomy. It is my hope that this book will be found suitable for introducing interested workers to this exciting field. Advanced topics will not be covered, as there are many excellent texts available.

Clinical Electroencephalography and Topographic Brain Mapping by Frank H. Duffy,Vasudeva G. Iyer,Walter W. Surwillo Pdf

Electroencephalography is truly an interdisciplinary endeavor, involving concepts and techniques from a variety of different disciplines. Included are basic physics, neuro physiology, electrophysiology, electrochemistry, electronics, and electrical engineer ing, as well as neurology. Given this interesting and diverse mixture of areas, the train ing of an EEG technician, a neurology resident, or an EEG researcher in the basics of clinical electroencephalography presents an uncommon challenge. In the realm of technology, it is relatively easy to obtain a technically adequate EEG simply by learning to follow a protocol and by correctly setting the various switches on the EEG machine at the right time. But experience has shown that the ability to obtain high-quality EEGs on a routine, day-to-day basis from a wide variety of patients requires understanding and knowledge beyond what is learned by rote. Likewise, knowledge above and beyond what is gained by simple participation in an EEG reading is necessary to correctly and comprehensively interpret the record. Such knowledge comes from an understanding of the basic principles upon which the practice of clinical EEG is founded - principles that derive from the various disciplines cited.

Cerebral Damage Before and After Cardiac Surgery by A.E. Willner Pdf

Despite numerous reports of cerebral damage in cardiac surgery, the subject has not been given the attention it requires. This book, with a preface by Torkel Aberg, will remedy that situation. The causes and incidence of pre- and post-operative cerebral damage are considered in the first section. Cardiac surgery patients frequently have preoperative cerebral impairment, not suprising when one considers the impaired circulation from a damaged heart and the brain's prodigious need for blood. Moreover, several perioperative aspects of surgical procedures have been considered as possible causes of cerebral dysfunction, for example: microbubbles, toxic by-products, non-pulsatile blood flow. The second section describes how imaging techniques (CT scan, MRI, regional cerebral blood flow imaging), and functional assessment techniques. (PET scan, EEG, BEAM and evoked potentials) can be used to measure cerebral damage. In the third section, psychometric and neuropsychological techniques are used to assess impaired mental abilities (abstract thinking, language, memory, visuo-spatial ability, mental flexibility, attention and concentration). The final section explores the relationship between cerebral dysfunction and psychopathology (several types of depression, anxiety, and aspects of organic brain syndrome, delirium and dementia).

Brain Imaging in Substance Abuse by Marc J. Kaufman Pdf

The last two decades have seen prodigious growth in the application of brain imaging methods to questions of substance abuse and addiction. Despite considerable advances in our understanding of the central effects of drugs provided by preclinical data, relatively little direct evidence was known of how substances of abuse affect the brain and other eNS processes in humans. Brain imaging techniques have allowed access to the human brain and enabled the asking of questions never before imagined. The positron emission tomography (PET) data ofVolkow and her colleagues in the late 1980s, showing the uptake and time course of cocaine's binding in the human brain, revealed for the first time the distinct sites of action of this drug. This work was extremely important because it showed clearly, through imaging a drug in the brain of a living human, that the time course of its action paralleled the behavioral state of "high. " This study marked a turning point in our understanding of drug-brain-behav ior interactions in humans. Many more investigations of drug effects on the structure and function of the human brain were soon to follow, leading to much better insights into brain systems. Brain imaging allowed for the direct assessment of structural and functional anatomy, biology, and chemistry in substance abusers.
