Teaching others reveals hidden structure in conceptual cognitive maps

The paper shows that natural speech can reveal the organization of conceptual cognitive maps, with disorganized speech linked to cognitive disorganization.

Disorganization impairs cognitive maps built from visual inputs

The paper shows that cognitive disorganization impairs the ability to form cognitive maps from visual input but not from linguistic structure.

A human multilineage gut organoid model for Parkinson disease

This paper develops a human gut organoid model incorporating PD-relevant cell types to study gut-brain pathways in Parkinson disease.

Apomorphine susceptibility and prenatal infection alter neurodevelopment, synaptic density and anticipatory behavior in rats

This study examines how polygenic susceptibility and prenatal immune activation affect neurodevelopment, synaptic density, and behavior in apomorphine-susceptible rats.

Normative Modeling of Brain Morphometry Across the Lifespan using CentileBrain: Algorithm Benchmarking and Model Optimization

The paper benchmarks and optimizes a normative modeling framework for brain morphometry across the lifespan using MFPR, showing excellent accuracy and stability.

Brain Networks Detectable by fMRI during On-Line Self Report of Hallucinations in Schizophrenia

The paper analyzes fMRI data to identify brain networks involved in radio speech listening and hallucination experiences in schizophrenia, finding speech-duration-dependent responses but not hallucination-duration-dependent ones.

Connectivity patterns of task-specific brain networks allow individual prediction of cognitive symptom dimension of schizophrenia and link to molecular architecture

The paper predicts individual schizophrenia symptom dimensions using functional brain networks and links these networks to molecular features like dopamine and serotonin systems.

Neural activity precedes conscious awareness of being in or out of a transient hallucinatory state

The paper shows that neural activity in the ventro-medial frontal cortex precedes conscious awareness of entering or exiting a transient hallucinatory state.

Evolutionarily developed connections compromised in schizophrenia

The paper examines how evolutionary changes in human brain connectivity overlap with schizophrenia-related changes, finding that human-specific connections are more involved in schizophrenia pathology.

Paracingulate sulcus morphology and hallucinations in clinical and non-clinical groups

The paper investigates whether shorter paracingulate sulcus length, linked to hallucinations in schizophrenia, is also present in non-clinical individuals with hallucinations.
