Abstract

In the last decade, the analysis of the synchronization between different brain signals has attracted much attention. In this context, detection methods of amplitude synchrony computed on time-frequency maps consider the baseline activity before stimulus onset. The present work introduces a new method to detect subsets of synchronized channels that do not consider any baseline information. It is based on a Bayesian Gaussian mixture model applied at each location of a time-frequency map. The work assesses the relevance of detected subsets by a stability measure.
