Magnetic Nanoparticles Restore Movement in Mice With Parkinson’s-Like Symptoms

Researchers used magnetic nanoplatelets in the subthalamic nucleus of Parkinson’s-like mice to stimulate deep brain circuits from outside the body.

An external magnetic field activated the particles and improved movement, pointing to a noninvasive neuromodulation approach.

The method is being studied as a potential alternative to implanted deep brain stimulation electrodes.

If it translates to humans, it could offer a less invasive and more flexible way to ease Parkinson’s symptoms.
