Schizophrenia, variability, and the Anna Karenina principle

The paper shows that higher variance in schizophrenia patients arises from greater perturbation counts, not disease-specific factors, highlighting the need to address broad damaging factors rather than specific pathologies.

Binomial order is a speech marker of psychosis and thought disorder

The paper examines binomial ordering preferences in speech as a potential marker for thought disorder in psychotic disorders, finding higher rates of atypical orderings in patients.

A spectrum of altered non-rapid eye movement sleep in schizophrenia

This study replicates group-level sleep EEG differences in schizophrenia and shows increased patient-to-patient variability in NREM metrics, with medication and age-related effects contributing to this heterogeneity.

Bias in group-level EEG microstate analysis

This study identifies biases in group-level EEG microstate analysis and proposes a paired analysis approach to reduce errors from subgroup topography differences.

Non-rapid eye movement sleep and wake neurophysiology in schizophrenia

This study identifies NREM sleep and wake EEG biomarkers associated with schizophrenia symptom severity and disease status.
