abstract = {Background: Schizophrenia has been primarily conceptualized
as a disorder of high-order cognitive functions with
deficits in executive brain regions. Yet due to the
increasing reports of early sensory processing deficit,
recent models focus more on the developmental effects of
impaired sensory process on high-order functions. The
present study examined whether this pathological interaction
relates to an overarching system-level imbalance,
specifically a disruption in macroscale hierarchy affecting
integration and segregation of unimodal and transmodal
networks.Methods: We applied a novel combination of
connectome gradient and stepwise connectivity analysis to
resting-state fMRI to characterize the
sensorimotor-to-transmodal cortical hierarchy organization
(96 patients v. 122 controls).Results: We demonstrated
compression of the cortical hierarchy organization in
schizophrenia, with a prominent compression from the
sensorimotor region and a less prominent compression from
the frontal-parietal region, resulting in a diminished
separation between sensory and fronto-parietal cognitive
systems. Further analyses suggested reduced differentiation
related to atypical functional connectome transition from
unimodal to transmodal brain areas. Specifically, we found
hypo-connectivity within unimodal regions and
hyper-connectivity between unimodal regions and
fronto-parietal and ventral attention regions along the
classical sensation-to-cognition continuum (voxel-level
corrected, p < 0.05).Conclusions: The compression of
cortical hierarchy organization represents a novel and
integrative system-level substrate underlying the
pathological interaction of early sensory and cognitive
function in schizophrenia. This abnormal cortical hierarchy
organization suggests cascading impairments from the
disruption of the somatosensory-motor system and inefficient
integration of bottom-up sensory information with
attentional demands and executive control processes
partially account for high-level cognitive deficits
characteristic of schizophrenia.},
