The colorful brain: compact visualisation of routine EEG recordings

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

Clinical EEG recordings are typically evaluated by visual analysis of the various waveforms. Besides the long learning curve, it is rather subjective and prone to human error. To assist in the visual interpretation, various quantitative techniques have been proposed. Here, we describe a triplet of features that quantify the spatial distribution of the various EEG waveforms and their coherence, represented as three time-frequency plots. The technique allows compression of 20 minutes of EEG recordings into a single picture, that captures various essential elements, including anterior-posterior diffentiation, reactivity to eyes opening and closing, and photic drving. In addition, it may detect disorders, including various manifestations of epileptiform discharges.
