title: Split-screen synchronized display. A useful video-EEG technique for studying paroxysmal phenomena.
abstract: Video-EEG is an indispensable and widely used technique for studying paroxysmal phenomena. We present a method of processing video recordings to compare the sequence of ictal manifestations of different episodes. Five presentations of two seizures recorded in each of five patients are shown, in which apparently different ictal features are strongly superimposed and stereotyped. Split-screen synchronized display is a simple and valid technique for studying and presenting particular semeiological aspects of epileptic seizures. (Published with videosequences).
