Orthogonalized partial directed coherence for functional connectivity analysis of newborn EEG
(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 ...
Performance evaluation of multi-component instantaneous frequency estimation techniques for heart rate variability analysis
(2012 , Conference Paper)
Accurate instantaneous frequency (IF) estimation of the non-stationary heart rate signal is important in quantifying the heart rate variability (HRV) measures. This study compares the effectiveness of four IF estimation ...
Time-frequency analysis of heart rate variability in neonatal piglets exposed to hypoxia
(2011 , Conference Paper)
To determine whether the sympathetic nervous system plays any role in the inter-individual variation of cardiovascular response to hypoxia in newborns, neonatal heart rate variability (HRV) analysis was used to assess ...
Generalised phase synchrony within multivariate signals: An emerging concept in time-frequency analysis
(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 ...
