Relationship between impulsivity, uncontrolled eating and body mass index: a hierarchical model

The paper examines the relationship between impulsivity, uncontrolled eating, and BMI using structural equation models and MRI data, finding associations between impulsivity traits and BMI via uncontrolled eating.

Evidence and urgency-related EEG signals during dynamic decision-making in humans

The paper uses EEG and a hierarchical Bayesian model to identify neural signals related to sensory evidence, decision variables, and urgency during dynamic decision-making, showing urgency reflects the product of sensory evidence and an evidence-independent signal.

Neural correlates of evidence and urgency during human perceptual decision-making in dynamically changing conditions

This study links neural activity in the human brain to decision-making parameters during a perceptual task, showing how drift rates and urgency signals are reflected in fMRI data.

Neuroanatomical Changes in White and Grey Matter after Sleeve Gastrectomy

This study examines brain structural changes after sleeve gastrectomy, finding increased grey and white matter density associated with weight loss and metabolic improvement.

Local vulnerability and global connectivity jointly shape neurodegenerative disease propagation

The paper uses an agent-based model to simulate neurodegenerative disease spread, showing how local vulnerability and network connectivity drive Parkinson's disease progression.

White Matter Hyperintensities and Cognitive Decline in de Novo Parkinson’s Disease Patients

This study finds that high baseline white matter hyperintensities (WMHs) in de novo Parkinson’s disease patients are linked to greater cognitive decline and cortical thinning compared to low WMHs or controls.

Network Connectivity Determines Cortical Thinning In Early Parkinson’s Disease Progression

The paper shows that cortical thinning in early Parkinson’s Disease correlates with connectivity to subcortical disease reservoirs, suggesting disease spread along neural networks.
