Cortical brain entropy architecture reveals multidimensional structure of schizophrenia

Area of Science:

• Neuroscience
• Psychiatry
• Systems Biology

Background:

• Schizophrenia lacks a unifying systems-level framework for its complex, multidimensional nature.
• Understanding the brain's functional organization is crucial for psychiatric disorder research.

Purpose of the Study:

• To introduce a cortical brain entropy architecture for characterizing schizophrenia.
• To investigate the spatial and hierarchical organization of functional entropy in the cerebral cortex.
• To establish a systems-level marker for schizophrenia heterogeneity.

Main Methods:

• Analysis of large-scale neuroimaging data.
• Characterization of spatial and hierarchical organization of functional entropy.
• Correlation of entropy alterations with network variations and clinical dimensions.

Main Results:

• The cortical brain entropy architecture effectively differentiates schizophrenia from healthy controls.
• Entropy alterations exhibit structured organization across the cortex, particularly within association networks.
• A quantitative link was established between macroscale cortical entropy and clinical symptom dimensions.

Conclusions:

• Cortical brain entropy architecture offers a compact systems-level marker for schizophrenia heterogeneity.
• The findings reveal coordinated disruptions within association networks in schizophrenia.
• This framework provides a quantitative link between brain entropy and clinical presentation in schizophrenia.
