The paper investigates how spatial collinearity among PET receptor maps affects multivariate molecular-enriched network estimation and finds that univariate modelling is more reliable.

This paper introduces the Bias Dominance Index (BDI) to diagnose whether neural network decisions are feature-supported or bias-driven, showing that high confidence can coexist with bias-driven decisions.

The paper develops a neuroreceptor-based modeling framework using PET data to model BOLD-derived brain activity and identifies neuroreceptor modules linked to brain networks and pharmacological effects.

The paper identifies multiple stable brain activation patterns for the same perceptual decision-making task using functional MRI and clustering analysis.

The paper quantifies how biophysical factors shape brain functional connectivity and shows molecular factors dominate graph-theoretic features while physical factors influence gradient features in neurological disorders.

The paper decodes reaction time and confidence across the cortex at the individual level, finding broader brain-behavior relationships than previously observed.

The paper quantifies the contribution of subject and group factors in brain activation using a new method applied to a perceptual decision-making task.

The paper identifies trial-to-trial variability in EEG patterns during a perceptual decision task and links these patterns to decision-making parameters.

The paper assesses reproducibility and variability in multi-modal, longitudinal brain networks across different modalities and tasks, finding structural networks more reliable than functional ones for individual identification.

The paper shows that neural activity during working memory tasks varies across trials and develops a method to classify these variations into distinct subtypes associated with different decision-making processes.

This study examines how severe traumatic brain injury alters brain connectivity in rats, finding that local network measures can identify subgroups with different structural changes and potential clinical outcomes.
