Transcutaneous Vagus Nerve Stimulation boosts evidence accumulation during perceptual decision-making

This study shows that transcutaneous vagus nerve stimulation (tVNS) improves perceptual decision accuracy by enhancing evidence accumulation, particularly when applied early in a task.

Phasic arousal sharpens, rather than amplifies, goal-dependent feedback control

This study shows that phasic arousal selectively sharpens goal-dependent feedback control during movement by amplifying task-relevant responses and suppressing irrelevant ones.

Non-invasive Stimulation of Contralateral Primary Motor Cortex Reduces the Amount of Skill Generalization to the Untrained Arm

This study shows that stimulating the contralateral primary motor cortex reduces skill generalization to the untrained arm, while not affecting retention, using rTMS in right-handed individuals.

Motor implementation of control and reward-based urgency regulation across impulsivity

The paper investigates how control-driven and reward-driven urgency regulation differ in individuals with varying impulsivity using motor system measurements.

White matter microstructure predicts effort and reward sensitivity

This paper uses diffusion MRI and computational modeling to show that white matter microstructure predicts individual differences in effort and reward sensitivity.

Short trains of transcutaneous vagus nerve stimulation increase online corticospinal excitability and pupil size in humans

This study shows that transcutaneous vagus nerve stimulation increases corticospinal excitability and pupil size during active stimulation but not after, with distinct temporal dynamics between the two effects.

Fronto-motor circuits linked to effort-based decision-making and apathy in healthy subjects

This study examines fronto-motor circuits related to effort-based decision-making and apathy in healthy individuals, finding associations between apathy scores and structural and effective connectivity in specific circuits.

Transcallosal generation of phase aligned beta-bursts underlies TMS-induced interhemispheric inhibition

The paper investigates the relationship between beta oscillations and TMS-induced interhemispheric inhibition, finding that TMS evokes phase-aligned beta bursts that mediate inhibition.

Task goals shape the relationship between decision and movement speed

The paper investigates how task goals influence the relationship between decision and movement speed, finding that coregulation occurs as a default but is replaced by a tradeoff when detrimental to reward rate.

Transcutaneous Vagus Nerve Stimulation Boosts Post-Error Accuracy During Perceptual Decision-Making

This study uses tVNS to investigate the role of the LC-NE system in perceptual decision-making, finding it improves accuracy without affecting reaction times, supporting the gain hypothesis.

Effects Of Extrinsic Reward Based Skill Learning On Motor Plasticity

This study investigates how extrinsic reward affects motor plasticity during skill learning, finding that reward reduces corticospinal output variability and correlates with individual reward sensitivity.

Non-invasive stimulation of the human striatum disrupts reinforcement learning of motor skills

This study uses tTIS to show that 80Hz striatal stimulation disrupts reinforcement learning of motor skills, while 20Hz does not, indicating a frequency-dependent effect on striatal function.

Movement characteristics impact decision-making and vice versa

The paper shows that decision-making and movement speed influence each other in a sensorimotor task, with faster movements affecting decision strategies similarly to faster decisions.

Post-error slowing reflects the joint impact of adaptive and maladaptive processes during decision making

The paper investigates how post-error slowing varies based on speed-accuracy tradeoff policies in different contexts and finds that it is only adaptive in a hasty context.

Reward timing matters in motor learning

This study shows that reward timing affects motor learning, with short delays leading to continuous gains and long delays causing early plateaus and reduced consolidation.

Hasty sensorimotor decisions rely on an overlap of broad and selective changes in motor activity

The paper shows that hasty decisions involve broad motor activity amplification and local suppression, improving signal-to-noise ratio in the chosen motor representation.

Reward boosts reinforcement-based motor learning

This study shows reward enhances motor learning beyond reinforcement feedback by specifically strengthening reinforcement-related motor adjustments, with effects lasting beyond the training session.

Motor training strengthens corticospinal suppression during movement preparation

This study shows that motor training strengthens preparatory suppression of corticospinal excitability, which is linked to faster movement initiation.

M1 disruption delays motor processes but not deliberation about action choices

This study disrupts M1 activity using cTBS and finds it delays motor processes but not deliberation in action choices.

Planning Face, Hand, and Leg Movements: Anatomical Constraints on Preparatory Inhibition.

The paper investigates how preparatory inhibition during movement preparation varies with anatomical distance between the target muscle and the movement effector.

Challenging the function of motor inhibition: Does it really assist action selection?

This study investigates whether preparatory inhibition aids action selection by comparing MEP suppression in choice and simple RT tasks.
