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.

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.

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.

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

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

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.

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