For evaluation of extra-cellular recordings with multi-electrode arrays (MEAs) an algorithm is needed to detect different types of cellular activity. The algorithm presented in this paper is based on correlation. It is an efficient and simple algorithm which is compared with the wave_clus toolbox. In contrast this toolbox is using wavelets for clustering the cell activity.
