Neural mechanisms of handedness for precision drawing: hand-dependent engagement of cortical networks for bimanual control

2025-11-18

Abstract excerpt

<h4>ABSTRACT</h4> Neural mechanisms underlying handedness remain poorly understood. We used functional magnetic resonance imaging (fMRI) to study performance of a visually guided drawing task with each hand. We hypothesized that the left superior parietal lobule supports drawing with either hand, and individuals with chronic peripheral nerve injury (PNI) to the dominant hand use the same mechanism as healthy adul...
