abstract = {Temporal neural synchrony disruption can be linked to a
variety of symptoms of major depressive disorder (MDD),
including mood rigidity and the inability to break the cycle
of negative emotion or attention biases. This might imply
that altered dynamic neural synchrony may play a role in the
persistence and exacerbation of MDD symptoms. Our study
aimed to investigate the changes in whole-brain dynamic
patterns of the brain functional connectivity and activity
related to depression using the hidden Markov model (HMM) on
resting-state functional magnetic resonance imaging
(rs-fMRI) data. We compared the patterns of brain functional
dynamics in a large sample of 314 patients with MDD
$(65.9\%$ female; age (mean ± standard deviation):
35.9 ± 13.4) and 498 healthy controls $(59.4\%$ female;
age: 34.0 ± 12.8). The HMM model was used to explain
variations in rs-fMRI functional connectivity and averaged
functional activity across the whole-brain by using a set of
six unique recurring states. This study compared the
proportion of time spent in each state and the average
duration of visits to each state to assess stability between
different groups. Compared to healthy controls, patients
with MDD showed significantly higher proportional time spent
and temporal stability in a state characterized by weak
functional connectivity within and between all brain
networks and relatively strong averaged functional activity
of regions located in the somatosensory motor (SMN),
salience (SN), and dorsal attention (DAN) networks. Both
proportional time spent and temporal stability of this brain
state was significantly associated with depression severity.
Healthy controls, in contrast to the MDD group, showed
proportional time spent and temporal stability in a state
with relatively strong functional connectivity within and
between all brain networks but weak averaged functional
activity across the whole brain. These findings suggest that
disrupted brain functional synchrony across time is present
in MDD and associated with current depression severity.},
