"Connectivity and dynamic function in the brain"
Proceedings IEEE International Symposium on Biomedical Imaging, 2003We wish to investigate the complex temporal dynamics of spatially distributed, highly interconnected brain regions, but available methods do not measure all relevant aspects of the system. We must take a convergent multidisciplinary approach, employing multiple methods and defining the relationships between disparate methods.

A methodology for dynamic functional connectivity
SPIE Proceedings, 2011Classical measures of functional connectivity assume that the stationarity of the time courses and the time-invariance of functional connectivity under investigation. These assumptions may not be valid in the real cases. Also, they are bivariate measures and may not provide the directional information flow between brain units.

Dynamic Functional Connectivity Using Heat Kernel
2019 IEEE Data Science Workshop (DSW), 2019Sliding and tapered sliding window methods are the most common approaches in computing dynamic correlations between brain regions. However, due to data acquisition and physiological artifacts in resting-state fMRI, the sidelobes of the window functions in spectral domain will cause high-frequency fluctuations in dynamic correlations.

Dynamic functional network connectivity alterations in obesity
Diabetes, Obesity and MetabolismAbstract Aims Obesity involves both metabolic and neural dysfunction, yet the temporal dynamics of brain connectivity remain unclear. This study applied dynamic functional network connectivity (dFNC) analysis to reveal time‐varying brain network patterns in obesity.
