EEG data acquisition.

This paper is a compressed version of a tutorial which was presented during the 1986 training course of the International Pharmaco-EEG Group, in Santa Margherita Ligure, Italy. The paper starts with a discussion of some basic features of the encephalograph, sketches the frequency modulation recording technique and presents some fundamental rules and concepts concerning digital data acquisition. Patient safety is a further aspect of the tutorial. Finally, two calibration procedures are outlined.

[Nystagmus analysis by computer (author's transl)].

Automatic quantitative nystagmus analysis by means of a digital computer primarily gives a lot of data. Analysis then means reducing this amount of numerical data to a few relevant results. Because the diagnostic importance is not known yet for all available nystagmus parameters, this implies the risk of losing essential informations. Therefore, limitations of the number of parameters as well as of the duration of the investigated intervals by the method of analysis have to be avoided. This then allows studying the diagnostic value of new parameters (e.g. of the fast components) or the time course of reaction intensity. From this point of view a method of quantitative nystagmus analysis is described.
