Non-invasive deep brain stimulation enhances motor learning

© Flyazure / 2023 EPFL Using a new, non-invasive brain-stimulation technique, scientists at EPFL show that it is possible to enhance the activity of deep brain structures and improve motor learning. The research opens up new ways for noninvasive treatments of brain disorders. _{Video: The Hummel lab showed improvements of motor learning in older adults by noninvasive neuromodulation of a deep brain region (striatum).

Stimulating the brain for neuromodulation is also crucial for advancing our understanding of how it works. By directly influencing neuronal activity and circuits, researchers can investigate causal relationships between brain activity and behavior and unveil the mysteries of neuroplasticity, learning and memory in the context of various neurological and psychiatric disorders.
