Magnetic brain stimulation

(March 12, 2015)  New technique could lead to long-lasting localized stimulation of brain tissue without external connections.

Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles — a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
