A structural MRI marker predicts individual differences in impulsivity and classifies patients with behavioral-variant frontotemporal dementia from matched controls

The paper develops a structural MRI signature of impulsivity using machine learning, validates it across multiple samples, and shows its diagnostic value in behavioral-variant frontotemporal dementia.

Multivariate analysis of multimodal brain structure predicts individual differences in risk and intertemporal preference

Less cortical complexity in ventromedial prefrontal cortex is associated with a greater preference for risky and immediate rewards

Subjective value, not a gridlike code, describes neural activity in ventromedial prefrontal cortex during value-based decision-making

The paper shows that vmPFC activity during intertemporal choice better reflects subjective value than a hexagonal gridlike code.

An fMRI-based brain marker predicts individual differences in delay discounting

The paper develops an fMRI-based brain marker predicting individual differences in delay discounting using machine learning, showing significant prediction accuracy in two independent studies.

The Future is Less Concrete than the Present: A Neural Signature of the Concreteness of Prospective Thought Is Modulated by Temporal Proximity during Intertemporal Decision-Making

The paper develops a neural signature to measure the concreteness of prospective thought and shows it decreases with temporal distance in intertemporal decision-making.
