Tiny Disks, Big Impact: Wireless Brain Therapy with Magnetic Nanodiscs
Your brain is a massive game of well-choreographed pinball. At every instant, a hundred billion neurons fire through a hundred trillion synaptic connections. It’s an incredibly complicated system ― and things can go wrong. In Parkinson’s disease, misfiring neurons cause tremors and uncontrollable movements. One possible treatment is Deep Brain Stimulation (DBS): using implanted electrodes that send electrical impulses to specific brain areas responsible for motor control, DBS essentially resets parts of the pinball board. By hijacking neural signals, it’s been shown to reduce symptoms and improve motor function. However, DBS’s applicability is limited by its invasiveness. The surgery can cause hemorrhages and infection, and the target, commonly a region called the subthalamic nucleus, is buried deep inside the folds of the brain.
