Mapping and Mending Dexterous Movement Control with Neurotechnology

Dexterous movement is a hallmark of human motor ability, enabling us to interact skillfully with our environment. The loss of this capability due to movement disorders, such as Parkinson’s disease or stroke, strips individuals of independence and quality of life. This talk explores the neural underpinnings of dexterity, focusing on how the nervous system integrates sensory and motor signals to achieve precise control. We then examine how these mechanisms break down in movement disorders, leading to impaired motor function. Finally, we turn to neuroengineering technologies which aim to restore movement in affected individuals. By leveraging advances in neural interfaces and wearable systems, we are seeking to design systems to repair motor function. Overall, we highlight our highly interdependent scientific and translational goals to understand and restore complex movement.
