This study identifies small but consistent anatomical correlates of negative symptom dimensions in schizophrenia, linking them to prefrontal cortical thickness and limbic subcortical volumes.

This study investigates how structural brain alterations in schizophrenia relate to network architecture, finding hub susceptibility and shared epicenters across disease stages and disorders.

This study examines structural brain heterogeneity in schizophrenia using multimodal MRI data from the ENIGMA dataset, finding higher frontotemporal heterogeneity and left parahippocampal homogeneity in patients.

The paper compares adaptive coding of reward in bipolar I disorder and schizophrenia, finding similar deficits in the right posterior caudate but more preserved coding in BD in anterior regions.

The paper investigates neural correlates of reward-cognition interactions and apathy in the psychosis continuum using fMRI and clinical scores.

This study finds that schizophrenia patients show increased random exploration linked to inflammation and disorganization symptoms.

This study compares apathy and reward system dysfunction in bipolar I disorder and schizophrenia, finding comparable apathy severity but distinct neural correlates.
