New Possibilities of Analysis in Electronystagmography

Abstract

The authors have introduced vectonystagmo-graphy for the computer analysis of electronystagmo-grams. The ψ angle determining the direction of the rapid eye movements and the $ angle between the first and the second, and between the first and the third channels have been measured. The variables have been defined. A programme has been prepared where the output data give information on each individual nystagmic movement and on total values. A detailed description of data collection and programming is given, plus examples of three-channel vecto-nystagmographic recording.
