abstract = {Functional connectivity (FC) refers to the statistical
dependencies between activity of distinct brain areas. To
study temporal fluctuations in FC within the duration of a
functional magnetic resonance imaging (fMRI) scanning
session, researchers have proposed the computation of an
edge time series (ETS) and their derivatives. Evidence
suggests that FC is driven by a few time points of
high-amplitude co-fluctuation (HACF) in the ETS, which may
also contribute disproportionately to interindividual
differences. However, it remains unclear to what degree
different time points actually contribute to brain-behaviour
associations. Here, we systematically evaluate this question
by assessing the predictive utility of FC estimates at
different levels of co-fluctuation using machine learning
(ML) approaches. We demonstrate that time points of lower
and intermediate co-fluctuation levels provide overall
highest subject specificity as well as highest predictive
capacity of individual-level phenotypes.},
