PRACTICAL GUIDE TO COMPUTER APPLICATIONS IN NEUROSCIENCES. Jan Bures, Ivan Krekule, Gustav Brozek. John Wiley & Sons, ChIchester - New York - Brisbane Toronto - Singapore (1982), 399 pp., ISBN 04711C0129. Price. f24.75. In the present book a comparative approach to software for applxatlons III neuroscxnces 1s stressed by means of numerous examples of ccaranonly used data handling procedures which are presented m several progranmungxrcdes. Hardware 1s discussed as far as necessary to orlent the reader. The volume 1s dlvlded Lnto three parts. The fxst part provides the essential background mfoxx&lon IIIa condensed manner: Chapter 1 gives a short overview of the procedures applied to on-lme analysis of signals 111neurosciences. Processing of time functions - predcminantly of electrophyslolcgxal sqxLs and behavioral recordings -, analysis of image data and autcnnatlonof experiments are mentioned. Chapter 2 m which the authors give a "short overview of hardware of laboratory computers" starts w~_ththe representationof numbers and general organlsatlon of a digital computer. Standardand specialazed peripheral devices are described with respect to their appllcatlons UI the field. Chapter 3 gives a short overview of the software of laboratory ccxqxters (machme code prcgrmg, assembly language, BASIC and FLXITAN). The second part represents the practical guide to prcqramtung laboratory ccmputers 111mchlne code and low level languages (Chapter 4) and 111higher level languages (Chapter 5). Chapter 6 1s concerned with debugging and testing. The contents concentrate on examples of computer programs derronstratmg the mxtlmportantprogr amrung technques and their fundamental blcmedxal and neuropsychologlcalappllcatlons. Each problem such as lnteractlve display of analog sqnals, display of data stored YI memory, simultaneous display of tm ylpUts, detection of events, peak detection, amplitude wxndow, prccesslng of dxcrete events, on-lule and off-lme hxstcgram construction, and evaluation of power spectra is illustrated by programs written of various levels (LAP 6, PAL 11, BASICandFORTRAN IV). The programs are explained mtextand comments 3n the program printouts The actual programs were developed for D.E.C laboratory CcarQxlters. However, they can be adapted to particular machines on any computer equipped with corresponding software. The third part (Chapter 7) revzws the main methods and applxatlon areas of signal processing 111neurosciences. It covers on-lme data processing analysis of neumnal sptie actlvlty, analysis of analog sqnals, pxture data prccesslng and autamatlon of experxments. The part 1s supplemented by btillography of representative references as well as sublect mdeex, author tiex and further reading This guide gives an excellent overview of the ccxqxter technques in the field of neurosciences. The emplasis 1s put on dldactx aspects of the programs. They are brief and easy to understand. With the present bcok the authors have indeed reached their goal to help neurosclentxts to master computer control and prqr-ng to a degree necessary for their work H.-W, Borchers Unlversitat des Dndes Hessen Fachberexh 19 3500 Kassel (F.R.G.)
