    Gene–environment pathways to cognitive intelligence and psychotic-like experiences in children

    Junghoon Park, Eunji Lee ... Jiook Cha
    Genetics, socioeconomic conditions, and family and school environments influence cognitive intelligence in children, and this impact may lead to the individual variability of the current and future PLEs.

    Mapping brain-behavior space relationships along the psychosis spectrum

    Jie Lisa Ji, Markus Helmer ... Alan Anticevic
    A data-reduced neuro-behavioral geometry in psychosis spectrum disorders mapped symptoms stably on to distinct functional brain regions and offers a framework for informing personalized treatment selection decisions.

    Elevated brain-derived cell-free DNA among patients with first psychotic episode – a proof-of-concept study

    Asael Lubotzky, Ilana Pelov ... Yoav Kohn
    Liquid biopsy methods utilizing brain-specific cell-free DNA methylation markers can detect brain cell death and potentially assist early detection and monitoring of schizophrenia.

    DNA methylation meta-analysis reveals cellular alterations in psychosis and markers of treatment-resistant schizophrenia

    Eilis Hannon, Emma L Dempster ... Jonathan Mill
    DNA methylation data can be harnessed to provide insights into molecular and phenotypic differences associated with the spectrum of psychosis diagnoses.
    1. Neuroscience

    Distinct hierarchical alterations of intrinsic neural timescales account for different manifestations of psychosis

    Kenneth Wengler, Andrew T Goldberg ... Guillermo Horga
    fMRI evidence for distinct hierarchical alterations in intrinsic neural timescales for different positive symptoms of schizophrenia support hierarchical perceptual-inference models of psychosis and suggest local increases in excitation-inhibition ratio.

    Characterization and prediction of clinical pathways of vulnerability to psychosis through graph signal processing

    Corrado Sandini, Daniela Zöller ... Stephan Eliez
    A novel methodical approach aimed at improving translation of network analyses to psychopathology provides an intuitive representation of longitudinal clinical pathways between symptoms and can assist in predicting prognosis.

    Resting-state gamma-band power alterations in schizophrenia reveal E/I-balance abnormalities across illness-stages

    Tineke Grent-'t-Jong, Joachim Gross ... Peter J Uhlhaas
    Resting-state MEG-activity and MRS-GABA/Glx measurements reveal that there is a significant shift in excitability during the course of schizophrenia, involving hyperexcitability during the onset and a reduction at chronic stages.

    Sleep EEG in young people with 22q11.2 deletion syndrome: A cross-sectional study of slow-waves, spindles and correlations with memory and neurodevelopmental symptoms

    Nicholas A Donnelly, Ullrich Bartsch ... Matt W Jones
    Measures of sleep features such as spindles and slow waves differentiate between young people with 22q11.2 microdeletion syndrome and healthy controls, and may mediate the relationship between this genotype and psychiatric symptoms.

    The effect of perinatal brain injury on dopaminergic function and hippocampal volume in adult life

    Sean Froudist-Walsh, Michael AP Bloomfield ... Oliver Howes
    Perinatal brain injury is associated with altered dopaminergic function and reduced hippocampal volume in adulthood in humans.

    Antipsychotic drugs selectively decorrelate long-range interactions in deep cortical layers

    Matthias Heindorf, Georg B Keller
    Cell type-specific effects of antipsychotic drugs in cortex could provide a basis for a functional screen of antipsychotic efficacy.
