abstract = {Schizophrenia is a devastating mental disease with an
apparent disruption in the highly associative default mode
network (DMN). Interplay between this canonical network and
others probably contributes to goal-directed behavior so its
disturbance is a candidate neural fingerprint underlying
schizophrenia psychopathology. Previous research has
reported both hyperconnectivity and hypoconnectivity within
the DMN, and both increased and decreased DMN coupling with
the multimodal saliency network (SN) and dorsal attention
network (DAN). This study systematically revisited network
disruption in patients with schizophrenia using data-derived
network atlases and multivariate pattern-learning algorithms
in a multisite dataset (n = 325). Resting-state
fluctuations in unconstrained brain states were used to
estimate functional connectivity, and local volume
differences between individuals were used to estimate
structural co-occurrence within and between the DMN, SN, and
DAN. In brain structure and function, sparse inverse
covariance estimates of network coupling were used to
characterize healthy participants and patients with
schizophrenia, and to identify statistically significant
group differences. Evidence did not confirm that the
backbone of the DMN was the primary driver of brain
dysfunction in schizophrenia. Instead, functional and
structural aberrations were frequently located outside of
the DMN core, such as in the anterior temporoparietal
junction and precuneus. Additionally, functional covariation
analyses highlighted dysfunctional DMN-DAN coupling, while
structural covariation results highlighted aberrant DMN-SN
coupling. Our findings reframe the role of the DMN core and
its relation to canonical networks in schizophrenia. We thus
underline the importance of large-scale neural interactions
as effective biomarkers and indicators of how to tailor
psychiatric care to single patients.},
