Variational bayes for spatiotemporal identification of event-related potential subcomponents

Abstract:

We propose a novel method for detection and tracking of event-related potential (ERP) subcomponents. The ERP subcomponent sources are assumed to be electric current dipoles (ECDs), and their locations and parameters (amplitude, latency, andwidth) are estimated and tracked fromtrial to trial.Variational Bayes implies that the parameters can be estimated separately using the likelihood function of each parameter. Estimations of ECD locations, which have nonlinear relations to the measurement, a...
