Sinopsis
This collection of papers reports on new developments in interdisciplinary research involving the slow electrical activity that can be observed and measured in the brain, the field potentials such as the EEG, slow potentials, DC-shifts and DC-levels. There has been a resurgence of interest in slow potential changes and their relationship to behaviour, including mental functions in humans, an area of study for many years passed over in favour of other aspects of brain electrical activity and techniques. It has been brought about by new computer methods of analysis and the development of the new biomagnetic measurement technique of magnetoencephalography. Neurophysiologists, neurologists, psychophysiologists and molecular neurobiologists discuss the "generator" problem and the interpretation of field potentials in this comprehensive overview of an important "new" field that holds great promise for understanding normal functions of the brain and also for diagnosing nervous system diseases and trauma.

Reseña del editor
DC-potential changes, comprising fast fluctuations and slow shifts, rep resent objective concomitants of neuronal processes in the brain. They can be recorded not only in animals, but also in humans under various conditions. As far as slow brain potentials are concerned, exciting results have been detected with respect to their correlation to psychophysiolog ical events. Although a large amount of data has been accumulated by psychophysiologists, neurophysiologists, and other scientists involved, the neurophysiological basis of these field potentials is still not clear, and remains controversial. Scientists from European countries participated in an interdisciplinary symposium in the summer of 1990, July 2 to 6, at the Friedrich Schiller University in Jena, which covered the field of slow brain potentials from the psychophysiological to the cellular level, including glial cells and microenvironment. From this conference the idea derived to present an up-to-date overview on important aspects of the field concerned. The Introductory Remarks are given to elucidate what is thought to be a "generator" of slow potentials of the brain. The large number of sources, implications of the "inverse problem" to analyze field potentials are taken into account.
