Abnormal Resting-State Brain Networks and their Relationship with
Cognitive Reappraisal Preferences in College Students with Depressive
Tendencies
Abstract
This study investigates resting-state brain network characteristics in
college students with depressive tendencies (DT) and their link to
cognitive reappraisal strategies. A group of 38 DT students and 41
healthy controls (HCs) were assessed using questionnaires on cognitive
reappraisal strategies, followed by alpha and beta frequency band EEG
feature extraction. Through complex network analysis, significant
reductions in cognitive reappraisal preferences were noted among DT
participants compared to HCs, alongside abnormalities in brain network
centrality, particularly in the frontal and limbic lobes across
different frequency bands. A notable correlation was found between the
preference for cognitive reappraisal in DT participants and significant
changes in graph indices. The findings highlight substantial alterations
in the resting-state brain networks of DT individuals, closely
associated with cognitive reappraisal strategy preferences. These
alterations may affect emotion regulation strategy choices, offering
insights into the neural mechanisms of emotional regulation difficulties
in DT.
