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.

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.

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.

Clinical Neurotherapy by Richard Soutar Pdf

Quantitative EEG (qEEG) has become an increasingly common method of assessment in the field of neurofeedback. The International Society for Neurofeedback and Research (ISNR) has issued a position paper advocating its widespread use within the field, and many entering the field gravitate toward its use because of its empirical value in the assessment and determination of protocols for intervention with neurofeedback. At the same time, the neuroimaging field has also increasingly taken an interest in qEEG and begun to employ it extensively in research alongside fMRI, because of its high temporal resolution and increasing spatial resolution resulting from recent enhancements such as low-resolution brain electromagnetic tomography (LORETA) imaging. This growing common use has provided a valuable new information source for the field of neurofeedback that can be applied at the research and clinical levels for an enriched analysis of client disorders. This chapter, on the one hand, is intended as an example of how those already engaged in qEEG might synthesize the emerging neuroimaging research with their own clinical experience, and is also an effort to present this topic in a generally understandable fashion. Those clinicians who are new to the field of neurofeedback or who are considering the use of qEEG at the clinical level are often intimidated by the complexity of the technology, and by the lack of basic guides to its implementation. Psychologists, counselors and medical professionals do not typically receive the technical training to prepare them for this new and powerful technology, which may come to play an important role in their respective professions. This chapter therefore is also meant to examine qEEG in a basic and comprehensive schema to help inform and initially guide such an audience in further exploration of the topic.
