A Methodological Framework to Assess the Accuracy of Virtual Reality Hand-Tracking Systems: A case study with the Oculus Quest 2

The paper presents a framework to assess VR hand-tracking accuracy, finding average positional error of 1.1cm, joint angle error of 9.6°, and delay of 38ms for the Oculus Quest 2.

Purkinje Cell Activity in Medial and Lateral Cerebellum During Suppression of Voluntary Eye Movements in Rhesus Macaques

This study investigates Purkinje cell activity in the medial and lateral cerebellum of rhesus macaques during antisaccade tasks, revealing distinct roles in volitional eye movement suppression.

Reward-driven enhancements in motor control are robust to TMS manipulation

The paper investigates how reward affects motor control by disrupting brain areas involved in reward processing and motor control, finding that transcranial magnetic stimulation did not alter reward-driven improvements in movement.

Reward-based improvements in motor control are driven by multiple error-reducing mechanisms

This study shows reward improves motor performance by enhancing feedback control and reducing motor noise through increased arm stiffness.

A neuroanatomically grounded optimal control model of the compensatory eye movement system

The paper develops an optimal control model of the compensatory eye movement system that successfully reproduces eye movement data across multiple conditions and explains non-linear reflex summation.

Domain-specific working memory, but not dopamine-related genetic variability, shapes reward-based motor learning

This study shows that working memory capacity, not dopamine-related genetics, predicts success in reward-based motor learning tasks.

The role of explicit strategies during reinforcement-based motor learning

This study investigates how explicit strategies influence reward-based motor learning, finding that strategy use is critical for successful learning and that its disruption impairs learning.

The relationship between reinforcement and explicit strategies during visuomotor adaptation

This study investigates how reinforcement and explicit strategies interact during visuomotor adaptation, finding that strategy-use is critical for reinforcement-based learning.
