Non-invasive brain stimulation meets nanotechnology



MIT Researchers Develop Wireless, Noninvasive Deep Brain Stimulation Approach (Med Device online):

“Scientists have introduced a novel method of administering brain stimulation that requires no implants or external connections. By injecting magnetic nanoparticles into the brain, researchers have found that they can manipulate neurons by applying external magnetic fields

While deep brain stimulation (DBS) has proven effective in assuaging the debilitating symptoms of Parkinson’s, it is reserved by clinicians as a last resort because of the device’s invasiveness and subsequent risk of stroke or infection. Experts have been researching ways to give the treatment a technical overhaul…

A team at MIT has been exploring the potential of magnetism to do away with the wires or implanted electrodes typically associated in DBS. Though transcranial magnetic stimulation is already in clinical use, it is only effective on brain tissue nearest to the surface. For maximum effect against hard to manage symptoms, the team is exploring ways to go deeper…”
