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…

Understanding of a brain spatial map based on threshold-free function dendrogramization
Hyekyoung Lee, Hyejin Kang, Youngmin Huh +2
Linear matrix factorizations (LMFs) such as independent component analysis (ICA), principal component analysis (PCA), and their extensions, have been widely used for finding releva…

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…
