Disrupted Sleep-Dependent Neural Oscillations and Transcriptomic Changes in the Cacna1g Loss-of-Function Mouse Model Implicated in Schizophrenia

Loss of CACNA1G disrupts sleep rhythms and gene regulation, creating a mismatch between brain state and behavior linked to schizophrenia.

The effect of sex on sleep EEG in typical and altered neurodevelopment

The paper examines sex differences in sleep EEG patterns among children with and without neurodevelopmental disorders, finding significant sex-based variations in sleep features but not in brain age predictions.

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.

Spindle Chirp and other Sleep Oscillatory Features in Young Children with Autism

The paper investigates spindle chirp and other sleep oscillatory features in young children with and without autism, finding significant differences in chirp negativity and coupling angles.

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.

Mapping Typical and Altered Neurodevelopment with Sleep Macro- and Micro-Architecture

The paper develops a sleep-based metric to quantify brain maturation using EEG data from children, showing high accuracy in predicting chronological age and detecting neurodevelopmental differences.

Sources of variation in the spectral slope of the sleep EEG

The paper replicates and extends findings on EEG spectral slope variation across sleep states in a large sample, identifying factors influencing slope estimates and their relationship to sleep parameters.

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.

Atypical neuromagnetic resting activity associated with thalamic volume and cognitive outcome in very preterm children

Neuromagnetic activation dynamics of stimulus-locked processing during a naturalistic viewing

This study uses MEG to map brain activation dynamics during naturalistic audiovisual stimuli, showing distinct patterns for visual and auditory stimuli classes.

Multiple constrained minimum variance beamformer (MCMV) performance in connectivity analyses

This study compares MCMV and LCMV beamformers for estimating electrophysiological connectivity, showing MCMV reduces signal leakage and preserves short lag interactions.

Atypical developmental features of cortical thickness trajectories in Autism Spectrum Disorder

The paper investigates atypical cortical thickness developmental trajectories in ASD using longitudinal neuroimaging data and finds that ASD shows decreased thinning in early adolescence and increased thinning later, associated with ADOS scores.
