EEG amplitude and correlation spatial decay analysis for neonatal head modelling
Odabaee M.; Layeghy S.; Mesbah M.; Azemi G.; Boashash B.; Colditz P.; Vanhatalo S.... more authors ... less authors (2012 , Conference Paper)There is an increased need to better understand the relation between brain structures and functions in newborns by using EEG source localization techniques. This requires a realistic head model that would take into account ... -
Generalised phase synchrony within multivariate signals: An emerging concept in time-frequency analysis
Omidvarnia A.; Boashash B.; Azemi G.; Colditz P.; Vanhatalo S. (2012 , Conference Paper)This paper introduces the notion of the instantaneous frequency (IF) based generalized phase synchrony in time-frequency analysis based on the concept of cointegration. This phase synchrony is then quantified by investigating ... -
Generalized Mean Phase Coherence for asynchrony abnormality detection in multichannel newborn EEG
Omidvarnia A.; Vanhatalo S.; Mesbah M.; Azemi G.; Colditz P.; Boashash B.... more authors ... less authors (2012 , Conference Paper)Inter-hemispheric asynchrony within the multichannel recordings of newborn EEG is associated with abnormal functionality of the newborn brain. Mean Phase Coherence (MPC) as a bivariate phase synchrony measure is widely ... -
Orthogonalized partial directed coherence for functional connectivity analysis of newborn EEG
Omidvarnia A.H.; Azemi G.; Boashash B.; O'Toole J.M.; Colditz P.; Vanhatalo S.... more authors ... less authors (2012 , Conference Paper)The aim of this study is to develop a time-frequency method and test its applicability to investigating directional cortical connectivity in the newborn brain considering the effect of volume conduction. We modified ...
