Incentive valence differentially engages open- and closed-loop basal ganglia circuits during movement initiation

The paper investigates how incentive valence engages different basal ganglia circuits during movement initiation, finding distinct neural patterns for reward and threat conditions.

Neural Control of Autonomic Arousal During Threat Anticipation Revealed by High-Resolution Cardiac Contractility

This study uses TREV to measure cardiac contractility during threat anticipation and finds it correlates with neural activity and emotional responses better than skin conductance responses.

Distinct amygdalar pathways to frontopolar cortex and medial temporal lobe support temporal memory for emotional events

The paper investigates how amygdala pathways to frontopolar cortex and medial temporal lobe modulate temporal memory for emotional events, finding distinct effects on memory accuracy and recency bias.

Cardiac-sympathetic state predicts action restraint, gated by demonstrated agency

The paper shows cardiac-sympathetic outflow predicts action restraint during a task, with effects modulated by reward and loss conditions and participant success.

Integrated Representations of Threat and Controllability in the Lateral Frontal Pole

The paper examines how different regions of the lateral prefrontal cortex represent threat and controllability during threat anticipation, finding that the lateral frontal pole uniquely integrates these signals.

Dissociation of putative open loop circuit from ventral putamen to motor cortical areas in humans I: high-resolution connectomics

The paper identifies a functional open loop circuit (OLC) in humans connecting ventral putamen to motor cortical areas via subcortical limbic nodes using high-resolution fMRI.

Dissociation of novel open loop from ventral putamen to motor areas from classic closed loop in humans II: task-based function

The paper dissociates the functional roles of a novel open-loop circuit and a traditional closed-loop circuit in the human brain during incentive-based motor tasks.

Decision heuristics in contexts exploiting intrinsic skill

The paper investigates whether heuristic decision-making in action selection correlates with skill in action execution, finding that heuristic users show skill advantages in spatially relevant aspects.
