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 investigates cognitive dysfunction in older HIV+ men using EEG and MRI, finding that attention-related neural circuits are more affected than inhibitory control circuits.

The paper investigates how the brain evaluates complex objects with multiple attributes, finding that ventromedial prefrontal cortex (vmPFC) and perirhinal cortex are involved in configural processing when value depends on the whole object rather than individual attributes.

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.

The paper shows that the human ventromedial frontal lobe is critical for value inference based on multi-attribute configurations, not elemental attributes.

The study investigates whether the ventromedial prefrontal cortex is critical for non-reinforced preference changes in a cue-approach training task, finding no group-level difference between participants with VMF lesions and healthy controls.
