Functional voxel hierarchy and afferent capacity revealed mental state transition on dynamic correlation resting-state fMRI
Dong Soo Lee, Hyun Joo Kim, Youngmin Huh +4
Voxel hierarchy on dynamic brain graphs is produced by k core percolation on functional dynamic amplitude correlation of resting-state fMRI. Directed graphs and their afferent/effe…

Volume entropy and information flow in a brain graph
Hyekyoung Lee, Eunkyung Kim, Hyejin Kang +4
Entropy is a classical measure to quantify the amount of information or complexity of a system. Various entropy-based measures such as functional and spectral entropies have been p…

Integrated multimodal network approach to PET and MRI based on multidimensional persistent homology
Hyekyoung Lee, Hyejin Kang, Moo K. Chung +3
Finding the underlying relationships among multiple imaging modalities in a coherent fashion is one of challenging problems in the multimodal analysis. In this study, we propose a…
