Controlling Brain Activity With Magnetic Nanoparticles

sciencehabit writes: Deep brain stimulation, which now involves surgically inserting electrodes several inches into a person's brain and connecting them to a power source outside the skull, can be an extremely effective treatment for disorders such as Parkinson's disease, obsessive compulsive disorder, and depression. The expensive, invasive procedure doesn't always work, however, and can be risky. Now, a study in mice (abstract) points to a less invasive way to massage neuronal activity, by injecting metal nanoparticles into the brain and controlling them with magnetic fields. The technique could eventually provide a wireless, nonsurgical alternative to traditional deep brain stimulation surgery, researchers say.

Well that de-escalated slowly

You know it's bad when "injecting metal nanoparticles into the brain and controlling them with magnetic fields" is LESS invasive.
