This study identifies distinct hippocampal cellular pathologies associated with social cognition in schizophrenia and affective psychosis, suggesting diagnosis-specific mechanisms.

The paper compares cellular biomarkers in psychiatric diagnoses using 3D hippocampal MR spectroscopy, finding both similarities and differences in symptom-related pathologies across affective and non-affective psychoses.

The paper identifies neurotransmitter systems linked to specific symptom dimensions in early psychosis using neuroimaging and PET data.

The paper identifies a transdiagnostic functional connectivity pattern in early psychosis linked to cognitive inflexibility and arousal dysregulation across different diagnoses.

The paper identifies a stable microstructural white matter signature associated with negative and somatic symptoms in early psychosis across two independent cohorts using PLS correlation.

The paper examines dynamic functional network connectivity in youth with psychosis spectrum symptoms using resting state fMRI data from the Philadelphia Neurodevelopmental Cohort.

The paper identifies structural brain differences in youth with psychosis spectrum symptoms compared to other groups, highlighting reduced cortical surface area and thalamic volume.

The paper examines age-related white matter microstructure differences in psychosis spectrum youth and finds that fractional anisotropy in the superior longitudinal fasciculus mediates cognitive development in typically developing youth but not in psychosis spectrum youth.
