Functional Connectivity
Whole-Brain Region to Region Approaches
Calculate the correlation (or partial
correlation) between a all pairs of regions).
∑ T −u
ρ ij = min { t=1 [y i(t + u) − ȳ i ][y j (t) − ȳ j ]
}
u∈U ˆσ i ˆσ j
Requires parcellation of the brain into
regions OR selection of a subset of regions.
May miss important associations due to this
selection process
May select finer or coarser map of regions
depending on objectives
Finer map may prompt the assessment of
whole brain topological properties (graph
methods)
