The transmitter and a system synchronizer, also described, are combined with a frequency-coherent receiver, an on-line minicomputer processor with oscillograpic display, and a novel collinear antenna to provide a highly portable VHF Doppler radar system. The system, complete with 5-degree azimuthal beamwidth antenna, weighs about 250 kg, and can be installed in remote locations in a few days. It has been used successfully in studies of equatorial and auroral ionospheric irregularities during the past several years.

DOWNLOAD EBOOK →This second volume of Basic and Clinical Aspects of Neuroscience is devoted to the various transmitter systems of the brain (classical and neuropeptides). In Part I the basic aspects are given, including a critical appraisal of the methods used yesterday and today to describe such neurotransmitter systems. Part II concentrates on the functioning in the body of these transmitter systems under physiologic and pathologic conditions. It goes on to show how neuroendocrine investigations may give insights into the functioning of neurotransmitter sys tems at least in the hypothalamus, to end with a chapter which assesses very critically the errors and deficiencies of the concepts and techniques used in the attempt to understand the functioning of the brain and the mind. The editors have been fortunate to have the eight chapters written by a team of investigators working under the direction of Professor G. Fink in the MRC Brain Metabolic Unit at Edinburgh University. We are grateful to him and his colleagues for their work in writing these chapters and for the fine result they achieved. I am grateful for the editorial work done by Professor E. E. Muller (Milan) and Professor M. O. Thorner (Charlottesville), which made this volume possible. Basle, May 1987 E.
