Burst-suppression is a classic pattern in ICU EEG. This repository re-implements using a very simple algorithm based on thresholding local variance, and described in Real-time segmentation of burst suppression patterns in critical care EEG monitoring, Westover et al., 2013. Compared to the orignal article, here we also reject segmented periods shorter than 0.2 seconds (they are usually artefactual).
